Answer:
b = 42° and c = 180-42 = 138°
Answer:
b) 42°
c) 138°
Step-by-step explanation:
Get 42° by looking at its vertical partner(vertical angle). Get 138° by subtracting 42 from it. Subtract 42 from the sum of the entire angle, and get 180° degrees.
Hope this helps! Have a wonderful rest of your day!

Answer:
[tex]54\:\mathrm{km/h}[/tex]
Step-by-step explanation:
Average speed is given by [tex]S=\frac{d}{t}[/tex], where [tex]d[/tex] is distance and [tex]t[/tex] is elapsed time.
Since we want the average speed of the entire trip, we need to total distance of the entire trip and the total time it takes for the entire trip.
What we know:
The trip took 2 hours (2:30 PM to 4:30 PM)The bus travelled [tex]22.5+42.8+42.7=108[/tex] kilometersSubstituting known values, we get:
[tex]S_{avg}=\frac{108\:\mathrm{km}}{2\:\mathrm{h}}=\boxed{54\:\mathrm{km/h}}[/tex]
A square pyramid. The square base has side lengths of 5 feet. The 4 triangular sides have a base of 5 feet and height of 6 feet.
What is the surface area of a pyramid with a base area of 25 ft2 and lateral faces each with areas of 15 ft2?
Answer:
85 ft^2
Step-by-step explanation:
Ok, the square base area is 5 x 5 = 25 square feet
the triangular sides have an area of (1/2)(5)(6) each, which is 15 square feet each, like you said.
To find the total surface area, you multiply the 15 square feet x 4 (there are 4 sides) and add the base.
15 x 4 = 60 + 25 = 85 square feet
Every 0.05 seconds a machine has a 0.0001% of activating. What is the probability of it activating each second.
Michael has a points card for a movie theater.
He receives 35 reward points just for signing up.
He earns 2.5 points for each visit to the movie theater.
He needs 70 points for a free movie ticket.
Write and solve an equation that can be used to determine v, the number of visits Michael must make to earn a free movie ticket.
Let the number of visits equal x.
Multiply the number of points by the points per visit.
2.5x
Add that to the points he got for signing up:
2.5x + 35
This needs to equal the total points needed:
2.5x + 35 = 70
Solve for x:
Subtract 35 from both sides:
2.5x = 35
Divide both sides by 2.5:
X = 14
He needs 14 visits
Find the value of x in the triangle shown below.
Answer:
√90
Step-by-step explanation:

-Chetan K
Answer:
B) [tex]x=\sqrt{90}[/tex]
Step-by-step explanation:
Pythagorean thm formula:
a² + b² = c²
Given:
a = 9
b = 3
c = x
Work:
a² + b² = c²
9² + 3² = x²
81 + 9 = x²
90 = x²
[tex]\sqrt{x^2} =\sqrt{90} \\x=\sqrt{90}[/tex]
which angles are complementary to each other ? select all that apply
Answer: ∠1 and ∠5
Step-by-step explanation:
You can see that all of the other angles are exactly 90 degrees. The remaining two are angles 1 and 5 which means that they have to be 90 degrees. Since they are together, they also look perfectly like a 90 degree angle.
Hope this helps :)

HELP ME ASAP!!! Tristan is stacking building blocks to make a tower. He takes a break when the tower is 5 2/5 feet tall, which is 1/3 of the height of the tower he wants to build. How tall is the tower when finished? Check all that apply
A. 1/3 x ? = 5 2/5
B. 1/3 ÷ 5 2/5 = ?
C. 5 2/5 x ? = 1/3
D. 5 2/5 x 1/3 = ?
E. 5 2/5 x 3/1 = ?
F. 5 2/5 ÷ 1/3= ?
Honestly, I'm not sure how to answer this, but I think this can help you.
Well if 5 and 2 fifths is one third of the total height of the building, then that means to find the total height of the building you need to times 5 2/5 by 3.
(I think F is an answer)

Find the Area of the shape
(Area of Composite Shapes)
Answer:
223.5 Km
Step-by-step explanation:
Area = Length x Width
Solving for Square Shape
8 · 6 = 48 km
Area = Length x Width
Solving for Rectangle Shape
9 · 14 = 126 km
Area = Length x Width ÷ 2
Solving for Triangle Shape
11 · 9 = 99 ÷ 2 = 49.5 Km
48 + 126 + 49.5 = 223.5 Km

which angles are supplementary to each other ? select all that apply
Answer:
∠1 and ∠5
Step-by-step explanation:
Angles 2, 3 and 4 are taking up 180 degrees because it is 1/2 of a circle. That means angles 1 and 5 are also taking up 180 degrees because both the angles add up to a straight line
Answer:
I hope you will understand my explanation
Step-by-step explanation:
Two Angles are Supplementary when they add up to 180 degrees. They don't have to be next to each other, just so long as the total is 180 degrees. Examples: 60° and 120° are supplementary angles.
A cylinder is sliced perpendicular to its circular base. What shape will the cross section be?
Answer:
RECTANGLE
