Question

Tell whether the angles are complementary or supplementary. Then find the value of x.

Answer 1

Complementary

x = 15

Explanation:

• Given angles are complementary, because their sum is 90°.

• Now, let us find the value of x.

• -> 3x° + 45° = 90°

• -> 3x° = 90° - 45°

• -> 3x° = 45°

• -> x = 45/3

• -> x = 15
