Question

How do you use law of sines given B= 150 degrees a= 10 b=3?

Answer 1

This problem has no solution!

Explanation:

Angle B is 150 degrees and is opposite the side with length 3.

However, side a = 10 which is greater than 3 and means that the angle opposite side a must be greater than 150 which is impossible since the angles within a triangle sum to 180.

Maybe there is a typo in the problem?

Hope that helps
