and the one long side is 9, short side is 8 and the other long side is c...

Use the pythagorean theorem to find unknown side c of the right triangle?
Didn't you just ask this question?





Pythagorean Theorem is a^2+b^2=c^2


Substitute:


8^2+9^2=c^2


Square the numbers


64+81=c^2


Combine like terms


145=c^2


Square root both sides


c is equal to approx 12.04
Reply:9^2 + 8^2 = c^2


81+64 = c^2


145 = c^2


Square root of 145 = c
Reply:c^2=a^2+b^2=8^2+9^2


c^2=64+81=145


c=12.04
Reply:c^2 = b^2 + a^2


so


c^2 = 9x9 + 8x8


= 81 + 64


= 145


C = sqrt(145) = 12.04
Reply:make sure you're specific about which long side is the hypotenuse and which is a leg (the triangle is a right triangle right?).
Reply:if c is the hypotenuse then the answer is





c^2=9^2+8^2 ==%26gt;


c^2=81+64 = 145





c=sqrt(145)
