Answer:

x = 32

Step-by-step explanation:

The sum of the measures of complementary angles is 90°.

x + 3 + 2x - 9 = 90

3x - 6 = 90

3x = 96

Answer:

x =  32

Step-by-step explanation:

Complementary angles add to 90 degrees

x+3 + 2x-9 = 90

Combine like terms

3x-6 = 90

Add 6 to each side

3x-6+6 = 90+6

3x = 96

Divide each side by 3

3x/3 = 96/3

x =  32
