Question

find the measure of the missing angle.

Explanation:

Step1: Recall angle - sum property

The sum of angles in a right - angled corner is 90°.

Step2: Set up the equation

Let the missing angle be \(a\). We know that \(a + 47^{\circ}=90^{\circ}\).

Step3: Solve for \(a\)

\(a=90^{\circ}- 47^{\circ}\).
\(a = 43^{\circ}\)

Answer:

\(43^{\circ}\)
