Complementary angles add up to 90 degrees. If one angle is 65 degrees, its complement is 90 - 65 = 25 degrees.
Complementary angles add up to 90 degrees. If one angle is five times the measure of the other, you can express their measurements as 5x and x. The original angle is x degrees and its complement is 5x degrees. Set the sum of the two angles equal to 90 and solve for x. 5x + x = 90 6x = 90 x = 15 The angle is 15 degrees. Its complement is 5(15) = 75 degrees. 75 + 15 = 90.

No. An angle is (90 minus its complement) degrees. The definition of the complement is "90 degrees minus the original angle".

There are two main uses. One is, in a complicated shape, to find the measure of an unknown angle using known values of other angles. The other is that trigonometric ratios are related to their supplement angles. Also, the sine of an angle is related to the cosine of of its complement.
