If measure angle 7 , recall that alternate interior angles have equal measures. Thus , the measures of angle is 65 degree. What is the measure of angle 9 degree?

Angle 9 = 65°

Step-by-step explanation:

Given:

Angle 7 = 65°

Angle 7 is alternate to Angle 9

Find:

Angle 9

Computation:

We know that

alternate interior angles are equal and angle 7 is alternate to angle 9

So,

Angle 7 = Angle 9

So,

Angle 9 = 65°
