okay, so the difference between the same side interior angles is 50, so the angles are 115 & 65, since 115 - 65 = 50, & they add up to become 180
So they are m∠115 , m∠65
2) lines a & b are parallel (given), m∠3 = x, m∠8 = 5x (given)
m∠3 + m∠8 = 180 (because they are supplementary angles)
x + 5x = 180
6x = 180
6x/6 = 180/6
x = 30
m∠3 = 30
m∠8 = 5(30) = 150
m∠8 = 150
hope this helps :D
