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
