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
