Pre Calculus Law of Sines
Three multiple choice questions: How many possible triangles for the following: A=85°; a=8cm; b=22cm; Find c in the figure below with the angle, alpha, is 116.57°; a=4.24; b=9.06; Find the measure of the angle between b and c in the figure below with the angle, alpha = 116.57°; a=4.24; b=9.06.

B and C
If we apply the law of sines we have that if a < b we should have the next solutions:

a < b*sin(A) We have no solution
a = b*sin(A) We have one solution
a >b*sin(A) We have two solution
In this case we have that
a < b...
