Answer:

Step-by-step explanation:

Area of a triangle = 1/2 * Base * height                     |  Plug in values

82.5 = 1/2 * 15 * height                                               | Multiple both sides by 2

165 inches = 15 * height                                             | Divide both sides by 15

Height = 165/15 = 11 inches
