Question 754310
Use the Pythagorean Theorem: a^2 + b^2 = c^2

In this case, the lengths of the hypotenuse (35") and one of the legs (28") are given. Plug the information into the formula, and solve to find the length of the remaining leg:

28^2 + b^2 = 35^2

784 + b^2 = 1225

Subtract 784 from both sides of the equation to isolate b^2:

b^2 = 1225 - 784

b^2 = 441 square inches

Take the square root of both sides of the equation to find b:

b = 21 inches
