Given the elevation, find height using trigonometry Can anyone help solve the following quickly please ?: > * A surveyor standing on a horizontal plain can see a volcano i the distance. > * The angle of elevation of the top of the volcano i $23$ degrees. > * If the surveyor moves $750$ m closer, the angle of elevation is now $37$ degrees. > Determine the height of the volcano using trigonometry.

**HINT**

By simple trigonometric rules, you need to solve the system for **h=height** and **d=distance**

$$\begin{cases}\frac{h}{d}=\tan 23°\\\\\\\\\frac{h}{d-750}=\tan 37°\end{cases}$$
