Answer: 48 yd

Explanation:

when trying to find one leg of a triangle given the other two, a^2 +b^2 = c^2 is applicable. A representing the first leg, B representing the second, and C representing the hypotenouse (a and b are interchangeable). So,

formula: a^2 + b^2 = c^2

insert given: 20^2 + b^2 = 52^2

exponents: 400 + b^2 = 2704

subtract: b^2 = 2704 - 400

simplify: b^2 = 2304

square root of both sides: b =
√(2304)

answer: b = 48
