Find the value of x. Then find the measure of each labeled angle.

x = 110; the labeled angles are 110º and 70º.


x = 70; the labeled angles are 110º and 70º.


x = 20; the labeled angles are 160º and 20º.


x = 20; the labeled angles are 60º and 20º.

Answer:

x = 70; the labeled angles are 110º and 70º.

Explanation:

The full degrees will add up to 180º. There are 2x and +40.

Equation:
2x+40=180

Solve:
2x+40=180\\\\180-40=140\\\\2x=140\\\\x=70

Since x=70, 70+40 will equal to 110.

Therefore, "x = 70; the labeled angles are 110º and 70º." is correct.
