Only <span>set Y = {6, 24, 36, 78, 84}, contains only whole numbers divisible by 6.
There were no options but this was the answer to this question on a quiz.
hope this helps!</span>
Apply the Pyth Thm twice:
diagonal of base is sqrt(4^2+6^2).
Then the length of diagonal AB is L = [sqrt(4^2+6^2)]^2 + [sqrt(1)]^2
I am not sure what the answer is but covert them into a decimal and then divide it
