Answer:
10.53
Step-by-step explanation:
Given :
Height of building = 17m
John's eye level = 2 m
Total height (including eye level) = 17+2 = 19m
Angle of depression, θ = 61°
Let distance between John's friend and building = d
Using trigonometry :
Tan θ = opposite / Adjacent
Tan 61° = 19 / d
1.8040477 = 19 / d
d = 19 / 1.8040477
d = 10.53
