    Wait... The length of AC is 30, and the length of AB is on-fourth the length of AC? Then the answer is not one of the ones you have listed.

    Well, if the length of AB is one fourth the length of AC, that means: \[AB = \frac{1}{4}AC = \frac{AC}{4} = AC \div 4\] That's pretty much it if you have the length of AC.
