In $$\Delta ABC$$, we have $$\angle A = 90^{\circ}$$, $$\angle B = \sqrt{7}^{\circ}$$, and $$BC = 1$$. What is the length of $$AB$$? (Ans: $$\sin \sqrt{7}^{\circ}$$)

Can you come up with a solution to this geometry problem that doesn't involve trigonometry, yet still comes up with the correct answer?
