Question

1. find the value of angle b if the pair of angles are complementary add up to 90°

Explanation:

Step1: Recall complementary - angle property

Complementary angles sum to 90°. Let the given angle be 63° and the unknown angle be \(b\). So, \(b + 63^{\circ}=90^{\circ}\).

Step2: Solve for \(b\)

\(b=90^{\circ}- 63^{\circ}\)

Answer:

\(27^{\circ}\)
