They are complementary
When the sum of two angles is 90 degrees, the angles are classified as complementary angles. This means that each angle, when added to the other, results in a right angle. For example, a 30-degree angle and a 60-degree angle are complementary because their sum is 90 degrees.
Complementary angles have a sum of 90 degrees.
two angles whose sum is 90 degrees is a complementary angle.

Sum of angles is 180, not 90
Two angles whose sum is 90 degrees are called complementary angles. Two angles whose sum is 180 degrees are called supplementary angles. A single angle of 90 degrees is called a right angle.
The sum of the angles of a triangle is 180 degrees. A right angle is 90 degrees. So the sum of the remaining two acute angles of a right triangle is 90 degrees.
Complementary and form a right angle
The sum of two complementary angles is 90 degrees.
Two angles are said to be complementary angles if their sum is 90 degrees. The angles A and B shown in the figure are complementary since their angle sum is 90°. + B = 90° B Two angles are said to be supplementary angles if their sum is 180 degrees. The angles A and B shown in the figure are complementary since their angle sum is 180°.
Two angles that have the same measure and sum up to 90 degrees are complementary angles. For example, if one angle measures 45 degrees, the other angle will also measure 45 degrees, and their sum will be 90 degrees.
The sum of complementary angles is 90°. The sum of supplementary angles is 180°. EXAMPLE : 27° is the complementary angle to 63° and the supplementary angle to 153°.
