Answer: To find the length of the hypotenuse of a right triangle, you can use the Pythagorean theorem. The theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides (the legs).
So, if the legs of the right triangle measure 2 cm and 5 cm, the hypotenuse c can be calculated as follows:
c² = a² + b²
c² = 2² + 5²
c² = 4 + 25
c² = 29
Therefore, the length of the hypotenuse c is the square root of 29.
c = √29
The answer is c = √29 which is the only one that is not squared, So the answer is (C) 29.
