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: Identify angle relationship

We know that a straight - line angle is 180°. $\angle NVS$ and the 110° angle are supplementary (form a straight - line).

Step2: Calculate $\angle NVS$

Let $m\angle NVS=x$. Then $x + 110^{\circ}=180^{\circ}$. Solving for $x$, we get $x=180^{\circ}-110^{\circ}$.

Answer:

$70$
