Question

after another wind change, the weathervane has turned an additional 20° and stopped at point t. how can you find m∠nvt? 90° + 95° = 180° 90° + 20° = 110° 90° - 20° = 70° 20° + 20° = 40°

Explanation:

Step1: Identify angle components

We see that $\angle NVE = 90^{\circ}$ and the additional turn from $E$ to $T$ is $20^{\circ}$.

Step2: Calculate $\angle NVT$

To find $\angle NVT$, we add the two - part angles. So, $\angle NVT=\angle NVE+\angle EVT$. Since $\angle NVE = 90^{\circ}$ and $\angle EVT = 20^{\circ}$, then $\angle NVT=90^{\circ}+20^{\circ}$.

Answer:

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