Question 1113338
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
{{{18/sin(B) = 11/sin(49)}}}
cross multiply
11*sin(B) = 18 * sin(49)
sin(B) = {{{13.5848/11}}}
sin(B) = 1.235, impossible angle, not a valid triangle
