I need help with how to solve this problem, not the actual answer. Thanks in advance!
(Capital letters are angles, lowercase letters are sides)
C a B
Determine the angles A and B given the following information:
side a = 15
side c = 22
The information given is not sufficient to define a unique triangle.
In addition you need the third side, or the angle B, or, see the next sentence.
If angle C is a right-angle, as is possibly indicated by the diagram, (and if it is you should say so),
then cos(B) = a/c etc. .
