Question

An angle measures 50° more than the measure of a complementary angle. what is the measure of each angle?

Answer 1

We solve the equation: a = 50 + ( 90 - a );
Then, a = 140 - a;
2a = 140;
a = 140/2;
a = 70 (it is the measure of one angle);
90 - 70 = 20 (it is the measure of another angle);
