Question

Core stretch An observer at $P$ stands between vertical towers $AB$ and $CD$. The distance $PB=40$ m, the angle of elevation of $A$ is $35^\circ$, and tower $CD$ is twice as high as $AB$. The angle of elevation of $C$ from $P$ is $50^\circ$. Find $40\text{ m}$ $B$ $A$ $P$ $D$ $C$ $35^\circ$ $50^\circ$ Give non-exact lengths and areas to 3 significant figures, and angles to 1 decimal place.

Accepted Answer

(a) $28.0$ m (b) $73.1$ m (c) $17.8^\circ$.
