Answer:
d = 41
Step-by-step explanation:
if the two lines are parallel, then 113 and 2x-5 are supplementary, which means that they add up to 180.
So:
113 + 2x - 5 = 180 =>
2x = 72
x = 36
Next step, we have three angles in the triangle that should add up to 180:
2x-5 + 2x + d = 180 with x=36
d = 180 - 139 = 41
so the angles are 72, 67 and 41
