Question

the wind changes again and the weathervane turns another 70°. now it points directly south.
which angle is adjacent to ∠tvs?
∠nvt
what is m∠nvs?
m∠nvs =

Explanation:

Step1: Analyze the composition of \(\angle NVS\)

\(\angle NVS\) is composed of a right - angle (\(90^{\circ}\)) and a \(70^{\circ}\) angle.

Step2: Calculate \(m\angle NVS\)

According to the angle - addition principle, \(m\angle NVS=90^{\circ}+70^{\circ}\).

Answer:

\(160\)
