Hi
Right Triangle: IF the 6cm and 8cm are the two legs of the Right Triangle:
  6^2 + 8^2 = hypotenuse^2
  36 + 64 = 100
 The hypotenuse = 10
 
Wish You the Best in your Studies.

given:
a right triangle -> so, use Pythagorean theorem
let the first dimension be , the second dimension be , and the third dimension be
if the first dimension measures and the second dimension measures , then the third dimension will be






so, the last dimension measures

            The solutions from both ladies are incomplete and therefore  INCORRECT.

            The correct solution is below. 


With the given data, the solution can be obtained for right triangle ONLY.

There are two possibilities.



(1)  The given sides are two legs.


     Then the third side, the hypotenuse, is   =  = 10 cm.



(2)  The longer side is the hypotenuse; the other side is one of the two legs.


     Then the other leg is   =  =  cm = 5.292 cm  (rounded).

Solved (correctly).
