An electrician is carrying a ladder horizontally around a corner from one hallway to another. One hallway is a foot wider than the other. If θ = 30°, find the exact length of the ladder.
A 8 + 2√3
B 6√3
C 12
D (− 18 + 8√3)/3

There is some information missing here, such as what angle is 30 degrees, and, I imagine, that the ends of the ladder touch the walls, as well as something else, because even then there is not enough information. If this is associated with a textbook, perhaps there is a similar problem elsewhere that included some additional facts you are expected to assume.

Please show the picture and anything else you omitted -- along with showing where you need help, because we won't just give you the answer!
