Write the algebraic expression described. Recall that two angles are complementary if their sum is 90 degrees. If one angle measures d degrees comma express the measure of its complement in terms of d degrees.

C = 90 - d

Step-by-step explanation:

We know that the sum of complementary angles is 90 degrees

i. e.

Angle 1 + angle 2 = 90°

As it is stated in the question that one angle is d then

d+C = 90

where C is complementary angle of C

This can also be written as:

C = 90 - d ...
