Question

how can you find m∠nvt?
90° − 20° = 70°
90° + 90° = 180°
20° + 20° = 40°
90° + 20° = 110°

Explanation:

Step1: Analyze the angle composition

\(\angle NVT\) is composed of a right angle (\(90^{\circ}\)) and an angle of \(20^{\circ}\).

Step2: Calculate \(\angle NVT\)

According to the angle - addition principle, \(m\angle NVT=90^{\circ}+20^{\circ}\).

Answer:

\(90^{\circ}+20^{\circ}=110^{\circ}\)
