To find BC, you use the Pythagorean Theorem (a^2 + b^2 = c^2).
22^2=484
120^2=14400
14400+484=14884
sqrt14884=122
Answer= 122

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

First you should subtract the first numbers. 82-33=49
Next, you need to subtract 49- the product, which is 49-35=14
Finally, check your work. 82-14-33=35
I think this is what you mean, at least?
