Answer:
48 inches
Step-by-step explanation:
Remember the Pythagorean theorem, where a and b are legs and c is the hypotenuse
a^2 + b^2 = c^2
a= 20
c = 52
now substitute in the given values
20^2 + b^2 = 52^2
400 + b^2 = 2704
solve using inverse operations
400 + b^2 = 2704
-400 -400
b^2 = 2304
b= sqrt(2304)
b=48
