To write the given phrase as an algebraic expression you can identify what does each part of the phrase mean:
59 less than: You have to substract 59 to the other part of the phrase
twice a number: as the number is n, twice a number is 2n
Then, you get the next algebraic expression:
SOH CAH TOA -> 
so.. which of those fellows do we use?
well, the triangle gives us
the angle, 15 degrees, for elevation angle
the adjacent side, 50m
and we want the opposite side, the slide
so...who has only, the angle, opposite, and adjacent sides?
well, low and behold, is Ms tangent
thus
notice, "x" in the picture, is the distance from the ground up to the top of the waterslide, using that triangle, what we're getting is just the distance, from the shorter slide, to the taller one, or x - 15
thus, the opposite side is x -15
