Question

angle of elevation of the top of a building from the foot of a tower is 30° and the angle of elevation of the top of the tower from the foot of the building is 60° if the height of the building is 15 M find the height of the tower​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

•Let the height of the tower be Xm.

The height of building= 15 m

So by tan30° ,

p/b = 15/b = 1/√3

b= 15√3m

. Now, the bases of both the triangles is same.

So for the height of tower,

tan60° = √3 = X/15√3.

X = 15×√3×√3

X = 45m
