Pythagorean Theorem

Use the diagram below to figure out how high up the side of the house the ladder reaches.

Kaden's Method
I can use the Pythagorean Theorem.
I plug the values into the theorem and solve for x.
The ladder falls at a point 23.69 ft. above the ground.
a2 + b2 = c2
82 + x2 = 252
64 + x2 = 625
x2 = 561
x = 23.69
