Supplementary angles add up to 180. The second is 120, 180-60=120

Answer:

The measurement of the second angle is
120\°

Explanation:

we know that

If two angles are supplementary

then

their sum is equal to
180\°

Let

x------> the measure of the second angle

so


x+60\°=180\°

Solve for x


x=180\°-60\°


x=120\°
