Two towns, A and B, are 32 km apart, and the distance between towns A and C is 14 km. Asviewed from a third town, at location C, the angle between towns A and B is 89 degrees. What isthe angle between towns A and C as viewed from town B (what is angle B)?Hint: you can use the sine law or whole vectors and a scale drawing, though the sine law isprobably easier.O 22.5 degreesO 28.6 degreesO 32.5 degreesO 25.9 degrees
