The length of one leg of a right triangle is 8 centimeters shorter than the

ra1l [238]

${34}^{2} + {b}^{2} = {42}^{2} \\ 1156 + {b}^{2} = 1764 \\ 1156 - 1156 + {b}^{2} = 1764 - 1156 \\ {b}^{2} = 608 \\ \sqrt{ {b}^{2} } = \sqrt{608} \\ b = 24.7$
I used the Pythagorean formula, which is a² + b² = c².
a² and b² are the two side legs while c² is the hypotenuse.
One of the side is 42 - 8 = 34 cm.
