Hello,
Lets solve this!
So here is the Pythagorean theorem Formula A2+B2=C2
5 two + B2 = 12 two
25 + B2 = 144
B2 = 119
Square root of B2 = Square root of 119
B ≈ ±10 feet
So the ladder has to be 10 feet on a horizontal angle from the base.
I hope that helped!

Hi There!
So we know that its 12ft. to get to the top of the building where the fire is. And the space there are going to put the ladder is 5ft. wide. You wouldn't want to put a ladder that is exactly 12ft. because the fire could either the ladder of made the firemen fall. You would want to have a laddet a foot or two smaller.
Answer - 10 or 11 feet would be most reasonable.
Hope This Helps :)
