Question

helicopter pad a local hospital builds a new helicopter pad as shown. if ( mangle1 = 43^{circ} ), what is ( mangle2 )?

Explanation:

Step1: Identify the relationship between angles

The two angles \( \angle1\) and \( \angle2\) are complementary (they form a right - angle, \(90^{\circ}\)).

Step2: Use the complementary angle formula

If \( \angle1+\angle2 = 90^{\circ}\), then \( \angle2=90^{\circ}-\angle1\).
Substitute \( \angle1 = 43^{\circ}\) into the formula: \( \angle2=90^{\circ}-43^{\circ}\).

Step3: Calculate the value of \( \angle2\)

\(90 - 43=47\).

Answer:

\(47^{\circ}\)
