Question

118° 30° v° v = ____

Explanation:

Step1: Recall angle - sum property

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

Step2: Set up equation

Let the unknown angle be \(v\). Then \(v + 118^{\circ}+30^{\circ}=180^{\circ}\).

Step3: Solve for \(v\)

\(v=180^{\circ}-(118^{\circ} + 30^{\circ})\)
\(v=180^{\circ}-148^{\circ}\)
\(v = 32^{\circ}\)

Answer:

\(32^{\circ}\)
