Aright triangle has legs with lengths of 5 cm and 12 cm. find the length of the hypotenuse.. a.. 7 cm. b.. 13 cm. c.. 17 cm. d.. 34 cm

This can be solved using the pythagorean theorem. The theorem is shown below:

c^2 = a^2 + b^2

The hypotenuse is c, so substituting the given values:

c^2 = (5)^2 + 12^2
c^2 = 25 + 144
c = sqrt(169)
c = 13

Therefore, the correct answer is B. 13 cm.

Hope i can you!
