Homework Help: Pre-Calculus follow up question Reiny

Posted by DW on Sunday, April 7, 2013 at 12:05pm.

Determine the number of triangles that can be formed with the given information.
and if it forms two possible triangles solve all unknown angles and sides

Angle A=116 degrees
a=10
b=11

but if you add 81.4 (measure of angle B) plus 116 (measure of angle A) you get 197.368 which is over 180 degrees....
so that would make measure of angle C negative which is why I'm confused
