      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 :)
