Question

what is the value of c? 31° submit

Explanation:

Step1: Use the property of vertical angles

Vertical angles are equal. The angle \(c\) and the angle composed of \(90^{\circ}\) and \(31^{\circ}\) are vertical angles.

Step2: Calculate the value of \(c\)

\(c = 90^{\circ}+ 31^{\circ}\)
\(c=121^{\circ}\)

Answer:

\(121\)
