Solve the missing side and angle in this triangle.
a = 11
b = 18
c = unknown
Angle A = 49 degrees
Angle B = unknown
Angle C = unknown
============
Assuming side a is opposite angle A, etc.:
Use the Law of Sines.
a/sin(A) = b/sin(B) = c/sin(C)

Solve the missing side and angle in this triangle.
Side a = 11
Side b = 18
Side c = unknown
Angle A = 49 degrees
Angle B = unknown
Angle C = unknown
:
Use the law of sines to find angle B

cross multiply
11*sin(B) = 18 * sin(49)
sin(B) =
sin(B) = 1.235, impossible angle, not a valid triangle
