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

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.

a^{2} + b^{2} = c^{2}

8^{2} + x^{2} = 25^{2}

64 + x^{2} = 625

x^{2} = 561

x = 23.69
