Answer:
120°
Step-by-step explanation:
A line must add up to 180°.
The sum of angles in a triangle also adds up to 180°.
Step 1: Find measures interior angles.
3x = 180
x = 60°
Step 2: Find measures of exterior angels.
x + 60 = 180
x = 120°

Answer:
210
Step-by-step explanation:
Formula I made up: (Don't copy it please) (x-1 + x-2 + x-3... until x-(x-1)
Add all answers possible. (4 true and falses with 2 different answers each.) (3 multiple choice with 4 possible outcomes.)
4 x 2 = 8 | 3 x 4 = 12 |
\ /
8 + 12 = 20
Do what I like to call Additional factorial. (it's a little different, so follow the formula above.)
x = 20
20 -1 + 20 - 2... 20-(20-1) = 210
19 + 18... + 1 = 210
Compare my answer to others if you get any because I am just in 8th grade and I am a nerd at math and I love it. Because I am in 8th grade, I have a slight possibility for being wrong. Enjoy the answer and thanks for letting me use my skills for the world. :)
Answer:
Step-by-step explanation:
<u>Volume of the prism is the product of its base area and height</u>
- V = AH
- V = 1260 cm³
- H = 18 cm
<u>Find base area:</u>
<u>Area of the trapezoid:</u>
<u>Substitute given values and solve for h:</u>
- 70 = 1/2(12 + 8)h
- 70 = 10h
- h = 70/10
- h = 7 cm
