Question

what is the value of the missing angle? 130° 50° 100° 25°

Explanation:

Step1: Recall angle - sum property of a triangle

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

Step2: Let the missing angle be \(x\)

We know two angles are 25° each. So, \(x + 25^{\circ}+25^{\circ}=180^{\circ}\).

Step3: Solve for \(x\)

\(x=180^{\circ}-(25^{\circ} + 25^{\circ})=180^{\circ}-50^{\circ}=130^{\circ}\)

Answer:

130°
