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

A^2 + b^2 = c^2and c is the hypotenuse

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 = 12so the other leg is 12 cm.
