No. An angle is (90 minus its complement) degrees. The definition of the complement is "90 degrees minus the original angle".
Complementary angles equals 180 degrees. If 3X + 2X = 180, then 5X = 180 so X=36 degrees.
Two complementary angles add up to 90 degrees. Hence, the problem can be set up and solved. Let x represent one angle and 5x represent the angle that is 5 times greater: x + 5x = 90 (simplify) 6x = 90 (next divide both sides by 6 to find the value of x [the smaller angle]) x = 15 (this is the smaller angle, next subtract 15 from 90 to find the greater angle) 90 - 15 = 75 (this is the greater angle which is 5 times that of its complement)

36 and 54 degrees.
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 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.
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.
