Same-side interior angles are supplementary, meaning that they add up to 180 degrees.

5x + 34 + 2x + 76 = 180

7x + 110 = 180

7x = 70

x = 10

Measure of angle A = 5(10) + 34 = 84 degrees

Hope this helps!! :)

answers: x=10 and angle a= 84 degrees
angles a and b are supplementary so to find x do 5x+34+2x+76=180
7x+110=180
7x=70
x=10
to find angle a substitute 10 into x
5(10)+34= 84
angle a=84
