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.

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

Step-by-step explanation:

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

Equation:

Solve:

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

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