Using the same picture as the last problem, how far is the refreshment stand form the parking lot? Round to nearest hundredth if necessary.
Let the distance from the parking lot to the beach be the altitude of the triangle = A
We have this relationship
10 / A = A /12 cross-multiply
10 * 12 = A * A
120 = A^2
The distance from the refreshment stand to the parking lot is
sqrt [ A^2 + 12^2 ] = sqrt [ 120 + 144 ] = sqrt 264 ≈ 16.25 m
