Since a^2+b^2=c^2 or c^2-b^2-a^2

Let's say that a=9

c=41.

41^2-9^2= 1600

Now, square root 1600, which will get you 40.

Therefore, 40 is a side length that will form a right triangle.

Hope this helped!

9 and 41 what is a third number to form a right triangle

1) sqrt ( 9² + 41² ) = 41.97618372 ( This is the number too )

2) sqrt ( 41² - 9² ) = 40

BBBBUUUUUTTTT there is ANOTHER possibility

if 9 and 41 are the LEGS of the triangle

9^2 + 41^2 = hyp^2 Hypotenuse = 41.976 is the third side

(the 40 third side answer is likey the correct one,,,,but you should realize that this solution is a correct answer TOO )
