Question

what is the measure of the missing angle?
enter your answer in the box.

Explanation:

Step1: Recall the sum of angles in a triangle

The sum of the interior angles of a triangle is \(180^{\circ}\).

Step2: Set up the equation

Let the missing angle be \(x\). Then \(x + 51^{\circ}+48^{\circ}=180^{\circ}\).

Step3: Solve for \(x\)

\(x=180^{\circ}-(51^{\circ} + 48^{\circ})\)
\(x=180^{\circ}-99^{\circ}\)
\(x = 81^{\circ}\)

Answer:

\(81^{\circ}\)
