Tamil Nadu Board Solutions for Chapter: Trigonometry, Exercise 25: Solved Example

Two trees are standing on flat ground. The angle of elevation of the top of both the trees from a point $X$ on the ground is $40°$. If the horizontal distance between $X$ and the smaller tree is $8 \mathrm{m}$ and the distance of the top of the two trees is $20 \mathrm{m}$, calculate the distance between the point $X$ and the top of the smaller tree.

$\left(\cos 40°=0.7660\right)$
