Can anybody tell me how to do the 2011 SEC Paper 2 Question 9?

Triangle ABE is similar to triangle ACD.. So put 57 over 133 and let that= x over 48+x. Then solve for x

Hi sean.hilliard2! Here is the worked solution for that question:
13 (a)
tan60 = h / x
square root(3) = h / x
h = square root(3)x
(b)
tan30 = h / 24  x
1 / square root(3) = square root(3)x / 24  x
3x = 24  x
4x = 24
x = 6
h = square root(3)x
h = square root(3)(6)
h = 6( square root(3))
Hope it helps :)
