Mathematics
1 answer:
bagirrra123 [75]3 years ago

Answer:

x=50

Step-by-step explanation:

A= 30+2x

B= x

Supplementary angles are angles that always add up to 180 degrees.

therefore, A + B=180 degrees

30 + 2x + x = 180: Now we solve

<em>30 + 3x =180 </em>

<em>subtract 30 from both sides</em>

3x=150

<em>divide by 3</em>

3x/3 = 150/3

x= 50
