Question

what is the complement of 40°? c =?

Explanation:

Step1: Recall the definition of complementary angles

Complementary angles add up to \(90^{\circ}\).

Step2: Calculate the complement

Let the complement be \(C\). Then \(C + 40^{\circ}=90^{\circ}\), so \(C = 90^{\circ}-40^{\circ}\).

Answer:

\(50\)
