set up a right triangle
the base is 15, hypotenuse 22, and the height is x. solve for x.
use the pythagorean theorum.
a^2+b^2=c^2
15^2+x^2=22^2
225+x^2=484
x^2=259
x=16.09 feet

This looks like a problem for the Pythagorean Theorem.
a^2 + b^2 = c^2
15^2 + b^2 = 22^2
225 + b^2 = 484
b^2 = 484  225
b^2 = 259
b = 16.09 feet
