1 answer:
Answer:
B. 28 inches
Step-by-step explanation:
We can use the Pythagorean theorem to solve this problem.
a^2 +b^2 =c^2 where a and b are the legs and c is the hypotenuse (diagonal)
16^2 + b^2 = 32^2
256 + b^2 =1024
Subtract 256 from each side
256-256 + b^2 =1024-256
b^2 = 768
Take the square root of each side
sqrt(b^2) = sqrt(768)
b = 27.7128129
Rounding to the nearest inche
b = 28 inches
