Answer:
10
Step-by-step explanation:
He makes $10 for each job he's done
here 8x and (2x+60) are corresponding angles
since line l1 and l2 are parallel, so the two angles will be equal
8x=2x+60
8x-2x=60
6x=60
dividing by 6
x=10
option D. 10 is correct
Check the picture below.
see below
x - c > dy
x > dy + c
a right angle
