Three support beams for a bridge form a pair of complementary angles. Find the measure of each angle. If (3x+3) (5x-9)

39 degrees and 51 degrees respectively.

Step-by-step explanation:

Two angles are complementary if their sum adds up to 90 degrees.

Given the pair of complementary angles formed by the three support beams:

3x+3 and 5x-9

Then:

3x+3+5x-9=90 degrees

Collect like terms

3x+5x=90+9-3

8x=96

Divide both sides by 8

x=12

Therefore, the measure of each angle is:

The measure of each angle is 39 degrees and 51 degrees respectively.

x=6 and x=3
