Answer:

30 feet

Explanation:

The ladder laying against the wall will create a right triangle.

The side lengths will be 18 and 24 and you will solve for the hypoteneuse which will be the length of the latter.

You can use the pythagorean theorm so


a^(2) +b^(2) =c^(2) so you plug in the values


18^(2)+24^(2) =c^(2) \\324+576=c^(2) \\900=c^(2) \\√(900) =\sqrt{c^(2) } \\30=c
