Answer:

x=9

Angle = 105

Step-by-step explanation:

The two angles are same side interior angles.  Same side interior angles on parallel lines equal 180 degrees

10x+15 +75 = 180

Combine like terms

10x +90 = 180

Subtract 90 from each side

10x+90-90=180-90

10x= 90

Divide by 10

10x/10 =90/10

x=9

The angle equals 10x+15

10*9 +15

90+15

105
