Answer:

a = 70

b=60

Step-by-step explanation:

Angle a and 110 are supplementary, which means they add to 180 degrees

a+ 110 = 180

Subtract 110 from each side

a+110-100=180-110

a = 70

The three angles of a triangle add to 180

a+ b+ 50 = 180

We know a = 70

70 + b + 50 = 180

120 + b = 180

Subtract 120 from each side

120-120 + b = 180-120

b = 60
