Does anyone know how to do this? If so please add steps. Geometry M1 Lesson 8 exit ticket

Answer 1

d = 41

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
