# For two complementary angles, find an expression for the measure of the second angle if the measure of first is:a) x ° b) ( 3 x − 12 ) ° c) ( 2 x + 5 y ) °

To determine

a)

To find:

The expression of the second angle of two complementary angles if the measure of first is x°.

Explanation

Definition:

If the sum of two angles is 90° then the angles are known as complementary angles. Each angle in the pair is the complement of the other angle.

Calculation:

The first angle is x°.

It is given that angles are complementary.

Let the second angle be y°.

The sum of x° and y° is 90°

To determine

b)

To find:

The expression of the second angle of two complementary angles if the measure of first is (3x12)°.

To determine

c)

To find:

The expression of the second angle of two complementary angles if the measure of first is (2x+5y)°.
