Answer 1

Answer:

°

Step-by-step explanation:

sum of supplementarty angles. =180. ,. that's why a+30+2a=180,. 3a=180-30,, 3a=150,, a=150/3=50. a=50 ,. a+30=50+30=80,,. 2a=2*50=100. It will help you

Answer 2

Answer:

Supplementary angles are two angles whose sum is 180°.

That means a+30+2a=180

Now, add a and 2a to get 3a. Transpose 30 to the other side and subtract 30 from 180.

3a=150

Now divide 150 by 3 to get a=50.

Now the angles were

a+30 which means 50+30=80

and 2×a=100
