Question

Find the angle of elevation from the base of one tower to the top of the second

Answer 1

This system can be represented by a triangle with base 350 m length and height 100 m length

The angle of elevation is given by:

$\tan ^{-1}(\frac{100}{350})=\tan ^{-1}(\frac{2}{7})\approx0.28\text{ rad }\approx\text{ 16\degree}$
