The measure of two supplementary angles = 180°.
Then m∠A = 104° and m∠B = 76°
According to the supplementary angles m∠A + m∠B = 180°
In the given question m∠A = (3x - 7)°,
m∠B = (2x + 2)°
then (3x - 7) + (2x + 2) = 180°
3x - 7 + 2x + 2 = 180°
5x - 5 = 180°
5(x - 1) = 180°
(x - 1) = 180 ÷ 5
x - 1 = 36
x = 37°
If x = 37°, then m∠A = 3(37°) - 7
= 111 - 7
= 104°
Similarly, m∠B = 2(37°) + 2
= 74 + 2
= 76°

When was the Panama Canal Built, and what is it used for?
Answers
To that end, in 1850 the United States and Great Britain negotiated the Clayton-Bulwer Treaty to rein in rivalry over a proposed canal through the Central American Republic of Nicaragua. The Anglo-American canal, however, never went beyond the planning stages. French attempts to build a canal through Panama (province of Colombia) advanced further. Led by Ferdinand de Lesseps—the builder of the Suez Canal in Egypt—the French began excavating in 1880. Malaria, yellow fever, and other tropical diseases conspired against the de Lesseps campaign and after 9 years and a loss of approximately 20,000 lives, the French attempt went bankrupt. In spite of such setbacks, American interest in a canal continued unabated. The Hay-Pauncefote Treaty of 1901 abrogated the earlier Clayton-Bulwer Treaty and licensed the United States to build and manage its own canal. Following heated debate over the location of the proposed canal, on June 19, 1902, the U.S. Senate voted in favor of building the canal through Panama. Within 6 months, Secretary of State John Hay signed a treaty with Colombian Foreign Minister Tomás Herrán to build the new canal. The financial terms were unacceptable to Colombia’s congress, and it rejected the offer.
President Roosevelt responded by dispatching U.S. warships to Panama City (on the Pacific) and Colón (on the Atlantic) in support of Panamanian independence. Colombian troops were unable to negotiate the jungles of the Darien Strait and Panama declared independence on November 3, 1903. The newly declared Republic of Panama immediately named Philippe Bunau-Varilla (a French engineer who had been involved in the earlier de Lesseps canal attempt) as Envoy Extraordinary and Minister Plenipotentiary. In his new role, Bunau-Varilla negotiated the Hay-Bunau-Varilla Treaty of 1903, which provided the United States with a 10-mile wide strip of land for the canal, a one-time $10 million payment to Panama, and an annual annuity of $250,000. The United States also agreed to guarantee the independence of Panama. Completed in 1914, the Panama Canal symbolized U.S. technological prowess and economic power. Although U.S. control of the canal eventually became an irritant to U.S.-Panamanian relations, at the time it was heralded as a major foreign policy achievement.

Cyclic migration is the movement of people within a given area and the area that they actually live while periodic migration can be defined as the movement of people in a given period of time to other areas.
What is migration?This is the term that is used to refer to the movement of people from one place to another place over a period of time.
The difference that would exist between these type of migration would be from the fact that periodic migration has to do with the large scale movement of organisms to an other area.
Meanwhile the movement that has to do with the temporary move to other areas by organisms is what is called the cyclic movement.

The layer of water covering the surface of the earth is called the hydrosphere.
However, the process during which [tex]CO_{2}[/tex] dissolved from the atmosphere into the hydrosphere or water is called the carbon cycle.

Give two examples of ways that ecosystems can change over time. write your answers in a complete sentence. one way that ecosystems can change over time is
Answers
Ecosystems, which are made up of a dynamic network of both living and nonliving entities, undergo steady change through time. New plants and animals either thrive or suffer when they are introduced to a region. Sometimes thriving species supplant native species.
The agroecosystem, human ecosystem, urban ecosystem, soil biological organisms, and rainforest ecosystem are examples of natural ecosystems. An ecosystem is a dynamic system that includes both living things like plants and animals and non-living items like the sun and soil.
Ecological succession or a shift in the environment refers to the process that causes organisms to vary in their structural appearance over time in a particular region. The species structure and habitat change are indicators of ecosystem change.
Many different biological species make up the diversity of a given area (species richness), while biodiversity refers to the measurement of the dominance of particular species in a given area (species evenness).
The release of soil nutrients owing to rainfall, a result of constant change in an ecosystem, and the development of plants due to favorable changes in the climate are examples of positive changes in the ecosystem. As a result of soil erosion brought on by rains breaking down the soil and climate change, which lowers air quality, the ecosystem has undergone unfavorable alterations.

In the geologic past, volcanic eruptions have had an impact on the availability of resources. How can volcanic eruptions impact the availability of resources?.
Answers
Volcanic eruptions impact the availability of resources by disrupting the sunlight from reaching producers.
What are volcanic eruptions?A volcano is an opening or rupture in the surface of the earth through which gases, volcanic ash, and hot liquid or semi-liquid rock can escape. They often develop when tectonic plates collide or diverge, but volcanic hotspots can also cause them to form in the midst of plates. When lava and gas are released from a volcano, often explosively, this is known as an eruption. A "glowing avalanche," which occurs when recently erupted lava slides down the flanks of a volcano, is the most hazardous type of eruption. They are capable of swift movement and can reach temperatures of 1,200 degrees Fahrenheit. Other dangers include lahars and ash fall (mud or debris flows). Food shortages and population dislocation are frequent effects of volcanoes.

Answers
The three main types of volcanoes that form and erupt differently are Cinder Cones, shield volcanoes, and composite cones.
What are volcanoes?
Volcanoes are conical-shaped structures that emerge from beneath the earth as a result of the movement of plate tectonics.
Under extreme pressure and temperature, magma is formed called lava which is erupted through a volcanic vent.
Lava consists of rock particles, hot gases, and vapors.
On the basis of shape and structure, volcanoes are classified as Cinder Cones, shield volcanoes, and composite cones.
Cinder Cones are reddish-brown structures having a crater or vent at the top.
Shield volcanoes have wide slopes. These volcanoes are known for lengthy lava flows that spill over the sides of the volcano.

Artificial reefs are structures constructed by humans in oceans that mimic some characteristics of natural reefs. Humans are trying to impact the oceans positively by creating artificial reefs as they decrease coastal erosion, enhance hydrodynamic for surfing, create a rich diversity of marine life, and keep the oceans ecosystem healthy.
While the other options are incorrect because:
Fishing is not an attempt to impact the oceans positively. Rather, it declines the wildlife population in oceans.

Answers
The measure of two complementary angles will always be 90°.
In the question m∠A = 53° and m∠B = 37°
According to the formula,
m∠A + m∠B = 90°
therefore (7x + 4)° + (4x + 9) = 90°
7x + 4 + 4x + 9 = 90°
11x + 13 = 90°
11x = 90° - 13
11x = 77
x = 77 ÷ 11
x = 7
If x = 7, then m∠A = 7(7) + 4

Finding the relative age of rock is important for understanding Earth's history. Relative age of rocks is defined as the geological age of a fossil rock, organism, or event relative to other rocks, organisms, features, or events.
Mudstones and shales are made up of silt and clay sized particles which are too small. Thus, the only difference between mudstone and shale is that the mudstones break into blocky pieces whereas, the shales break into thin chips.
