Question

What is the height of the flag pole?

Answer 1

Explanation:

assuming that the triangles are similar, which I can't by what is shown in the picture, but I'm guessing that there are more instructions off screen , that say they are.

' = feet

" = inches

h / 20' = 4'-2" / 3'-4"

just use inches for this, it's easier

h / 240" = 50" / 40"

h = 240 ( 50 / 40 )

h = 300"

h = 25'

Answer 2

Explanation:

comvert units into one unit

4ft 2in = 4 + 2/12 ft

3ft 4in = 3ft + 4/12ft

Know that the ratio of tan(x) = O / A

and set up proportions

`(ba)/(ac) = (h)/(rt)`

solve for h
