Question

find the complementary angle of 47°. 43° 33° 23° 13°

Explanation:

Step1: Recall complementary angle formula

Complementary angles sum to \(90^\circ\). Let the complementary angle be \(x\), so \(x + 47^\circ=90^\circ\).

Step2: Solve for \(x\)

Subtract \(47^\circ\) from both sides: \(x = 90^\circ - 47^\circ = 43^\circ\).

Answer:

A. \(43^\circ\)
