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° + 90° = 180° 90° + 20° = 110° 20° + 20° = 40°

Explanation:

Step1: Identify angle measures

We know $\angle NVE = 90^{\circ}$ and the additional turn is $20^{\circ}$.

Step2: Calculate $\angle NVT$

$\angle NVT=\angle NVE + 20^{\circ}=90^{\circ}+20^{\circ}$

Answer:

$90^{\circ}+20^{\circ}=110^{\circ}$
