I love houses, so i'll answer this.
4/3 = x/18
4 times 18= 72
3 times x = 3x
3x=72
x=24 feet

Let height of building be h
Angle of elevation is Ã, say.
tan à = 4 / 3
tan à = h /18
h /18 = 4 / 3
h = 18 x 4 / 3
h = 24
House is 24 ft tall.

you can solve it with a proportion
4 x
-- = --
3 18
then you cross multiply
(4)(18) = (3)(x)
simplify it
72 = 3x
divide both sides by 3
24 = x
the house is 24 ft tall
