Question

A triangle has sides A, B, and C. The angle between sides A and B is `pi/12`. If side C has a length of `7` and the angle between sides B and C is `pi/12`, what is the length of side A?

7

Explanation:

This is an isosceles `triangle ABC` with `angle C=angle A=pi/12`,

with equal opposite sided c = AB = 7 = BC = a..
