Answer: A, B, D, C, and E. I hope this is right, since it asked for rational numbers.
Step-by-step explanation:
Answer:
72°
Step-by-step explanation:
180-3x=2x
5x=180
x=36
Angle CBE = 2(36) = 72
If you are saying that the hypotenuse is 10 cm the you have to solve the following equation using the Pythagorean theory.
4^2 + b^2 = 10^2
16 + b^2 = 100
16 - 16 + b^2 = 100 - 16
b^2 = 84
Find 
Answer:
116
Step-by-step explanation:
8.2 / 2 = 4.1
a = 
0.5 x 8.2 x 5.6736 = 23.2618
23.2618 x 5 = 116.309 = 116
