Step-by-step explanation:

Given,

∠b is five times ∠a

Then, b=5a........(1)

As, a and b are supplementary

∴a+b=180°  

According to question,

∠a+∠b=180°

= a + 5a = 180°

⇒ 6a = 180°  

⇒ a = 30°

∵ b = 5a

∴b=5*30°

⇒b=150°

Answer 2

Answer:

A = 30

B = 150

In supplementary angle the sum is equal to 180°.

B is 5 times of A.

Let's A = 30

5 times of 30 = 150

Sum = 150+30=180.
