Question

An angle measures 80° more than the measure of a complementary angle. What is the measure of each angle?

Answer 1

Supplementary angles sum to 180 degree  

Let one angle be x  

Then the other angle is x+80  

Summing the 2 angle gives  

x+x+80=180

2x+80=180

2x=180-80

X=50

Thus the angles are 50 degree and 50+80= 130 degree
