The leg of the hypotenuse of a right triangle is 13 cm. The length of one leg is 5 cm. Find the length of the other leg.
A) 14 cm
B) 144 cm
C) 8 cm
D) 12 cm
5^2 + b^2 = 13^2 25 + b^2 = 169 b^2 = 169 - 25 b^2 = 144 b = sqrt 144...if u take sqrt of both sides, it eliminates the ^2 b = 12....so the other leg is 12 cm.
