Question

find the measure of the missing angle. answer attempt 1 out of 2 a =

Explanation:

Step1: Recall angle - sum property

The sum of angles in a right - angled configuration is 180°. Here, one angle is 90° and another is 51°.

Step2: Set up the equation

Let the missing angle be \(a\). Then \(a + 90^{\circ}+51^{\circ}=180^{\circ}\).

Step3: Solve for \(a\)

\(a=180^{\circ}-(90^{\circ} + 51^{\circ})\)
\(a = 180^{\circ}-141^{\circ}\)
\(a = 39^{\circ}\)

Answer:

\(39^{\circ}\)
