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
