Question

The two palm trees are of equal heights and are standing opposite each

other on either side of the river, which is 80 m wide. From a point O

between them on the river the angles of elevation of the top of the trees

are 60° and 30°, respectively. Find the height of the trees and the

distances of the point O from the trees.

Good afternoon​

Answer 1

Let two trees AB =CD

so, length of three = AB=CD

also,

width of the river = 80m

so, BC=80m

let point O be point between the trees

good afternoon

Answer 2

Explanation:

Tan 30 = 1/√3

Tan 60 = √3

Height of palm trees = 20√3 m

distance of point O from AB = 20 m

Distance of point O from CD = 60 m
