Question

find the missing angle

Explanation:

Step1: Use the property of supplementary angles

Supplementary angles sum to \(180^{\circ}\). Let the missing angle be \(x\). Then \(x + 121^{\circ}=180^{\circ}\).

Step2: Solve for \(x\)

\(x=180^{\circ}-121^{\circ}\)
\(x = 59^{\circ}\)

Answer:

\(59\)
