Question

The three angles together below are complementary. Use angle addition to solve for X.

Answer 1

x = 29

Explanation:

The 3 angles are complementary and sum to 90°

Sum the 3 angles and equate to 90

x + 1 + x - 1 + x + 3 = 90 , that is

3x + 3 = 90 ( subtract 3 from both sides )

3x = 87 ( divide both sides by 3 )

x = 29
