Complimentary angles are two angles that add up to 90o. It the sum of two angles is 90o, and one is twice as big as the other, then we can make up a little equation to solve for that larger angle (a). It might look like this: 90o = a + ( a / 2 ) As our larger angle (a) was said to be twice as large as our smaller angle, our smaller angle (a/2) is half as large as the larger angle. 90o = 3a / 2 180o = 3a a = 180o / 3 = 60o Our mystery angle is a 60o angle. The smaller one is 30o. The larger angle is twice the smaller, and they two sum to 90o. Our work checks.
60 degrees.

An angle and its complement sum to ninety degrees. 90-52=38
30 degrees
An angle and its complement have to add to 90 degrees. 77 and 13 add to 90. 13 is the complement of 77. You will also be doing supplement. They add to 180.
The complement is 60 degrees.
40 degres
An angle and its complement add to 90 degrees. Hence an angle of 41 degrees has 49 degrees as its complement.
The complement of an angle C is (90 - C) So the complement of an angle of 17.7° is (90 - 17.7) = 72.3°
The complement of an acute angle A is the angle 90° - A. The complement of 13° is 77°.
15°
The complement is how much you have left after you subtract the first angle from 90 degrees.

60 degrees.

The supplement of A is 180 - A The complement of A is 90 - A So, 180 - A = 2*(90 - A) + 20 or 180 - A = 180 - 2A + 20 So A = 20 degrees
