The measure of an angle is five times the measure of its complementary angle. What is the measure of each angle?

GalinKa [24]

Answer:

150 degrees

Step-by-step explanation:

Let the supplement = x
So the angle you want is 5x
Then [x + 5x] = 180 because they are supplementary.
Solving. 6x = 180. Then x = 30.
So the angle is 5x = 5×30 = 150 degrees
