Question

Help answer please!!

Answer 1

h = 19.7 ft.

Explanation:

Use the Pythagoras Theorem

`(Hypotenuse)^2 = (Base)^2 + (Perpendicular)^2\\\\(20)^2=(3.5)^2+(h)^2\\400=12.25+h^2\\400-12.25=h^2\\387.75=h^2\\`

Now we take square root on both sides,

`√(387.75) =√(h^2)\\19.69=h\\h=19.7\ ft\\`

so the value of h equals 19.7 ft.
