Question

A 32-foot ladder leans against a building so that the top of the ladder touches the building at a point 23 feet above the ground. To the nearest tenth of a foot, how far from the bottom of the building is the bottom of the ladder?
Please help! I'll medal!

Answer 1

Use the Pythagorean theorem for this.
a^2+b^2=c^2
The ladder is c
The wall is b
The ground is a
Rearrange the equation so that you can solve for a.
a^2=c^2-b^2
Substitute values.
a^2=32^2+23^2
Simplify
a^2=1024-529
a^2=495
Square both sides.
√a^2=√495=22.2
