Question

A vertical pole of $20m$ cast a shadow of $15m$ on ground at the same time a tower cast a shadow of $75m$ on ground. Find the height of the tower.

Answer 1

We can see that all angles in both Triangles are Equal

in $△AEC$ and $△BDC$

So, $\tan C=\frac{20}{15}=\frac{h}{75}\Rightarrow h=100$
