Question

I’m a little stuck and I’m not sure how to proceed. Answer number 3

Answer 1

In order to know the height of point B

the angle between the points is 30°

`\sin \text{ 30}=(x)/(32)`
`x=\sin (30)\cdot32=16`

Therefore the height of point B is

`H_B=40+16=56`

The height of point F is located is the same as the point B

ANSWER

Height of point B= 56ft

Height of point C= 56ft
