Answer:

x = 18.75

Explanation:

The angles are alternate interior angles and alternate interior angles are equal when the lines are parallel

3x-10 = 65-x

Add x to each side

3x-10+x = 65-x+x

4x-10 = 65

Add 10 to each side

4x-10+10 = 65+10

4x = 75

Divide each side by 4

4x/4 = 75/4

x = 18.75
