Question

The angle of elevation of a tree is 65 from a point on the ground if the distance between the point and the tree is 30 ft find the height of the tree rounded to the nearest whole number

Answer 1

The angle of elevation is 65 and distance between point and tree is 30 ft.

The diagram is obtained as

To determine the height of tree,

Use the trigonometric function.

`\sin 65=(h)/(30)`
`h=30*\sin 65^(\circ)=27.2`

Hence
