Question

1. find the missing angle(s).

Explanation:

Step1: Recall triangle angle sum

The sum of angles in a triangle is \(180^\circ\).

Step2: Calculate missing angle

Let the missing angle be \(b\). Then \(50^\circ + 60^\circ + b = 180^\circ\). So \(b = 180^\circ - 50^\circ - 60^\circ = 70^\circ\).

Answer:

\(70^\circ\)
