Answer:
b.
Step-by-step explanation:
Each of the provided angles are also a part of linear pairs, so 180-145=35
180-100=80
35+80=115
To solve for the final angle/the one they are wanting
180-115=65
Answer:
The answer is 120
Step-by-step explanation:
3 places. 6 options in the first place, 5 options in the second place, and then 4 in the last place. Because one option is used every time you pick one.
6x5x4=120
Answer:
20 5/6 ft
Step-by-step explanation:
5 3/5 = 28/5
1 4/5 = 9/5
V = l * w * h
210 = l * 28/5 * 9/5
210 = l * 252/25
multiply both sides by 25/252
5250/25 = l
Reduce
20 5/6 = l
20 5/6 ft
A right angle = 90 degrees
A round angle = 360 degrees
1. 3 x 90 = 270 degrees
2. 4 x 90 = 360 degrees
3. 1 1/2 x 90 = 135 degrees
4. 2 1/3 x 90 = 210 degrees
5. 2/9 x 360 = 80 degrees
6. 3 3/8 x 360 = 1,215 degrees
Observe that
In the original equation, divide both sides by 
:
