Answer:

m<CAO = 56

Step-by-step explanation:

When two parallel lines are intersected by a transversal, the same-side interior angles are supplementary, meaning that their angle measures add up to (180) degrees. Using this information, substitute in the given values and solve for the unknown,

(m<DOA) + (m<CAO) = 180

Substitute,

3x + 40 + 2x = 180

Simplify,

5x + 40 = 180

Inverse operations,

5x + 40 = 180

     -40    -40

5x = 140

/5     /5

x = 28

Now substitute the value of (x) back into the given expression for the value of (<CAO). Solve to find the numerical value.

<CAO = (2x)

= 2(28)

= 56

I want to build a shed that is 16‘ x 20‘ while I am measuring the foundation I measure the diagonal from one born to another measurement is 29 feet is the corner 90°?

Answers

Answer:

the corner is not 90 degrees

Step-by-step explanation:

To confirm if the corner is 90 degrees, we would use Pythagoras theorem

The Pythagoras theorem : a² + b² = c²

where a = length

b = base

c =  hypotenuse

16² + 20² =  

256 + 400 =656

find the square root of 656

= 25.6 feet

If the corner was 90 degrees the diagonal should be 25.6 feet and not 29 feet

If a || b || c and m∠9 = 76°, find the measure of each missing angle.

Answers

Answer:

m∠1 = m∠3 = m∠5 = m∠7 = m∠9 = m∠11 = 76°

m∠2 = m∠4 = m∠6 = m∠8 = m∠10 = m∠12 = 104°

Step-by-step explanation:

Vertical angles are congruent.  When lines are parallel, corresponding angles are congruent.

m∠1 = m∠3 = m∠5 = m∠7 = m∠9 = m∠11 = 76°

m∠2 = m∠4 = m∠6 = m∠8 = m∠10 = m∠12 = 180 - 76° = 104°

The Pony Express
Chapter 1
At A Nation's Crisis
The Pony Express was the first rapid transit and the first fost mail line across the continent from the Missouri River to the Pacific Coast. It was a system
by means of which messages were carried swiftly on horseback across the plains and deserts, and over the mountains of the far West It brought the
Adontic coost and the Pacific slope ten days nearer to each other.
It had a brief existence of only sixteen months and was supplanted by the transcontinental telegraph. Yet it was of the greatest importance in
binding the East and West together at a time when overland travel was slow and cumbersome, and when a great national crisis made the rapid
communication of news between these sections an imperative necessity.
The Pony Express marked the highest development in overland travel prior to the coming of the Pacific railroad, which it preceded nine years.
It, in fact, proved the feasibility of a transcontinental road and demonstrated that such a line could be built and operated continuously the year
around-a feat that had always been regarded as impossible.
The operation of the Pony Express was a supreme achievement of physical endurance on the part of man and his ever faithful companion, the
horse. The history of this organization should be a lasting monument to the physical sacrifice of man and beast in an effort to accomplish
something worthwhile. Its history should be an enduring tribute to American courage and American organizing genius.

a. MJK 101°
b. JK = 799
C.
JK = 140.5°
JK = 50.5°
d.

Answers

Answer:

a) 101°

Step-by-step explanation:

arc HK = 2(39.59°) = 79.18°

arc JH = 180°

arc JK = 360° - 180° - 79.18° = 100.82°

JK = 101°

The correct answer is option (A) 101°

What is an inscribed angle?

"It is an angle in a circle formed by two chords that have a common end point on the circle."

For given example,

m ∠J = 39.59°

We know, the measure of an inscribed angle in a circle equals half the measure of its intercepted arc.

⇒ m(∠J) = (1/2) × arc KH

⇒ arc KH = 2 × 39.59°

⇒ arc KH = 79.18°

Also, arc HJ = 180°

We know for given figure,

⇒ arc JK + arc KH +arc HJ = 360°

⇒ arc JK + 79.18° + 180° = 360°

⇒ arc JK + 259.18° = 360°

arc JK = 100.82°

⇒ mJK ≈ 101°

Therefore,  mJK = 101°

The correct answer is option (A) 101°

z = 34.05

Step-by-step explanation:

Sorry if the explanation is messy

answer

x=29.44

y=48.08

z=68

Step-by-step explanation:

opp/adj = tan(30)

17/x = tan(30)

x = 29.44

hyp^2 = x^2+y^2

hyp^2 = (29.44)^2 + (17)^2

hyp^2 = 867 + 289

hyp = 34

opp/hyp = Sin(45)

34/y = Sin(45)

y = 48.08

adj/hyp = Cos(45)

z/(48.08) = Cos(45)

z = 68

what is the volume of a cylinder with a length of 6 inches and a width of 5 inches?

Answers

It is the indeed process of formation. You see you must first drop the em and so on.
The basic formula of cylinder volume is V = *pi* r^2 h. You need to first find the radius, which can also be the width. 5^2 = 25. Next you need to find the height, and multiply it altogether.

3.14 x 25h = 78.5h (h will stay since the height is not given)

seconds, the rock
reaches a maximum
height of 256 feet. Four
seconds later, the rock

Write an equation to
model the scenario.

Answers

Answer:

Step-by-step explanation:

2.256 = 4x

So first Maya throws the rock from the 192-foot cliff into the ocean.

After 2 seconds, the rock reaches a maximum height of 256 feet;

so 2 seconds, 256 feet - 2.256

After 4 seconds, the rock reaches the ocean.

so 4  seconds, it reaches the ocean but we don't know how many feet. ( x )-- 4 seconds, x feet.equation: 2 . 256 = 4 . x

Good luck!

The required equation that represents the scenario is x = 64 * 2 + 256 * 4

Given that,
Maya throws a rock straight up from the edge of a 192-foot cliff and into the ocean. After two seconds, the rock reaches a maximum height of 256 feet. Four seconds later, the rock enters the ocean. To write an equation to model the scenario.

What is the equation?

the equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.

Here,
let the total distance covered by the rock vertically be x,
now,
Distance traveled by the rock vertical upward in 2 seconds = 2 * (256 - 192)
                                                                                          = 2 * 64
Distance traveled by the rock vertical downward in 4 seconds = 4 * 256
Total distance,
x = 2 * 64 + 4 * 256

Thus, the required equation that represents the scenario is x = 64 * 2 + 256 * 40.
