Question

The angle of elevation of the sun, when the length of the shadow of a tree 3 times the height of the tree, is​

Answer 1

Step-by-step explanation:

Let AB be the tree and AC be its shadow, So as per question, shadow of a tree is \begin{aligned}\sqrt{3}\end{aligned} times the height of tree. Let h be the height of the tree, then 

\begin{aligned}

\frac{AB}{AC} = tan\theta \\

=> \frac{h}{\sqrt{3}h} = tan\theta \\

=> tan\theta = \frac{1}{\sqrt{3}} \\

=> \theta = 30^{\circ}

\end{aligned}
