Question 360893
Two complementary angles add up to 90 degrees. Subtract 77.5 from 90. and multiply the result by two.

90-77.5 = 12.5

12.5 x 2 = 25

25 is the second angle. Subtract it from 90 and you will find the measure of the first angle.

90-25 = 65  First angle= 65   Second angle= 25

I hope that I clarified it for you :]
