anonymous · Answer

i'm really confused on how to solve for these types of questions

anonymous · Answer

this is not law of sines if all the sides are given... you need to use the law of cosines...

in the drawing, angle A is given side c is given and side a is given.
Do you see that these given conditions can determine two different triangles?  This is why they call it ambiguous.
