Correct Answer: 30 ft

Solution :

Let $h$ be the height of the tree and $x$ be the breadth of the river.
From the above figure we get,
$\tan60°=\frac{h}{x}$
⇒ $\sqrt{3}=\frac{h}{x}$
⇒ $x=\frac{h}{\sqrt{3}}$----------(equation 1)
Also, $\tan30°=\frac{h}{x+20\sqrt{3}}$ 
⇒ $\frac{1}{\sqrt{3}}=\frac{h}{x+20\sqrt{3}}$
⇒ $x=h\sqrt{3}–20\sqrt{3}$ ---------(equation 2)
Now equalising the values of $x$ from both
