Could someone please help explain with these questions please? I don't understand how I could do this and I am just confused... If 0 degrees ? A ? 180 degrees, find two values for two angles if SinA =0.7431 In triangle ABC a=11.4 c=8.1 and Angle C =36 degrees What is the measure of Angle A? (this one I think is a ambiguous case but I don't know what to do with it) Please Help!! Thanks!!

The other value will be 180  first value. For the second, use the law of sines (sinC)/c = (sinA)/a to get sinA, then use the same procedure as in question one to get the 2 values for A.
