Question

ken leans a 12-foot ladder against his house. He places the ladder so that the base is 5 feet from the house. How far up does the ladder reach?

Answer 1

you can use Pythagorean theorem

Answer 2

so it would be a^2+b^2=c^2

Answer 3

correct

Answer 4

so you have
5^2 + h^2 = 12^2 solve for h

Answer 5

so would i get 25=144

Answer 6

wait i see what i did wrong it would be h^2+25=144 and you subtract 25 from each side and squareroot 119

Answer 7

so you have h^2 = 119
so the answer for h = sqrt119

Answer 8

yeah so i wouldnt go any further from that

Answer 9

or you can put it in decimals which = 10.9
