i am alright in geometery but not great and i dont understand how to work this problem or i would find the answer myself. the problem is i cant find out how to work it at all neither on the internet or in my textbook!!!

You can put this solution on YOUR website! The lines are perpendicular.
so they intersect at right angles = 90 degrees
x+20 =90
x=90-20
x= 70 deg. option D
