Question

what is the complement of 40°? c = ?°

Explanation:

Step1: Recall the definition of complementary angles

Complementary angles add up to \(90^{\circ}\). Let the complement of \(40^{\circ}\) be \(C\).

Step2: Set up the equation

\(C + 40^{\circ}=90^{\circ}\)

Step3: Solve for \(C\)

\(C=90^{\circ}-40^{\circ}\)
\(C = 50^{\circ}\)

Answer:

\(50\)
