Question

A 29-foot ladder is leaning against a building. The base of the ladder is 20 feet from the side of the building. How high does the ladder reach along the side of the building?

Answer 1

use pythagorean theorem to solve for x

Answer 2

\[\huge x = \sqrt{29^2 - 20^2}\]

Answer 3

what is the pyethagorean theorem before you plugged numbers into it?

Answer 4

That S^2 = r^2 + r^r
and that r^2 = s^2 - r^2
I a right triangle where s = the side accross the 90 degree corner and the r = any of the other two sides of the triangle.
