Question

after another wind change, the weathervane has turned an additional 20° and stopped at point t
how can you find m∠nvt?
90°−20°=70° 90°+20°=110°
90°+90°=180° 20°+20°=40°

Explanation:

Step1: Analyze the angle composition

We know that one part of the angle \( \angle NVT\) is \(90^{\circ}\) (from \(N\) to \(E\) perpendicular part) and the additional part is \(20^{\circ}\) (from \(E\) to \(T\)).

Step2: Calculate the measure of \( \angle NVT\)

To find \(m\angle NVT\), we need to add these two angles together. So, \(m\angle NVT=90^{\circ}+ 20^{\circ}\)

Answer:

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