Question

The measure of the angles

Answer 1

Answer: a = 150
              b = 30

Remember: supplementary angles always add up to 180 degrees. Therefore, using this information, you can easily form your equation.

Form your equation. Since a is five times b, a = 5b. 
5b + b = 180               Combine like terms
6b = 180                     Divide by 6 to both sides
b = 30                         Answer!

Substitute (30) for b in a = 5b to find a.
a = 5(30)                    Simplify
a = 150                      Answer!

Answer 2

A is 150
B is 30
