Question

From the top of the tower 30 m height a man is observing the base of a

tree at an angle of depression measuring 30 degree. Find the distance
between the tree and the tower.

Answer 1

Explanation:

it makes 30 degree with the horizontal.

so it makes 90-30=60 degree with the tower.

let x be the distance between tower and tree.

`(x)/(30) =tan 60=√(3) \\x=30√(3)`
