Question

The foot of a ladder is placed 18 feet from a wall. If the top of the ladder

rests 24 feet up on the wall, find the length of the ladder.
26 feet
27 feet
29 feet
O 30 feet

Answer 1

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`

Answer 2

I'm not sure

I think its 30 or 26
