Question

A tree casts a shadow that is 18 feet in length. If the angle of elevation is

28, which of the following best represents the height of the tree?

A. 6.8 ft
B. 7.4 ft
C. 8.2 ft
D. 9.6 ft

Answer 1

It forms a Triangle, in which base is shadow, and height of the tree is perpendicular.

So, Tan Ф = P / B
Tan 28 = P /18
0.53 * 18 = P [ Tan 28 = 0.53 ]
P = 9.6

In short, Your Answer would be Option D

Hope this helps!
