Follow your right angle triangle laws. For this question we will use the Tangent rule. Tangent Rule : Tan(angle) = opposite/adjacent.
So : Tan19 = Opposite/32 (Multiply 32 by both sides to take the 32 out of the denominator)
32 * Tan19 = Opposite (Evaluate in calculator)
11.01 = Opposite (Which is the height)
