Question

Alright guys one last question for you, tried using the Pythagorean Theorem but the answer didn't make sense at all.

Answer 1

by using Pythagoras law

p²+b²=h²

p²+36²=39²

p²=39²-36²=225

p=√225=15

remaining length=15unit

Answer 2

`\boxed{15}`

Explanation:

First using the Pythagorean theorem, we know the hypotenuse
`(c^2)` is 39 and one of the legs
`(b^2)` is 36. So we would have:

`a^2+36^2=39^2=a^2+1296=1521\\\text{Subtract 1296 on both sides:}\\a^2=225\\\text{find the square root of 225}\\√(225)=15`

So we have our answer as
`\boxed{15}`

Hope this helps.
