Question

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

Answer 1

Answer:

by using Pythagoras law

p²+b²=h²

p²+36²=39²

p²=39²-36²=225

p=√225=15

remaining length=15unit

Answer 2

Answer:

$\boxed{15}$

Step-by-step 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:

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

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

Hope this helps.
