A 32 -ft ladder leans against a building so that the angle between the ground and the ladder is 76 ∘ . How high does the ladder reach on the building? Round to the hundredths. (2 decimal places)

i think that you should ask google for the answer to that problem because if we don't know it google does

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
