Question

what is the missing angle?

Explanation:

Step1: Recall angle - sum property

The sum of interior angles of a triangle is 180°.

Step2: Set up the equation

Let the missing angle be \(x\). Then \(x + 75^{\circ}+50^{\circ}=180^{\circ}\).

Step3: Solve for \(x\)

\(x=180^{\circ}-(75^{\circ} + 50^{\circ})=180^{\circ}-125^{\circ}=55^{\circ}\).

Answer:

55
