I THINK THE QUESTION MIGHT BE INCORRECT OR NOT EXPLAINED PROPERLY 
IN LEFT-HAND SIDE, THERE IS NO INFORMATION ABOUT ANGLE B 
 
AND NO INFORMATION (RELATION)  IS GIVEN ABOUT A and B angles 
IN BOTH THE SIDE THERE IS DIFFERENT VARIABLES {no constraint are given}
 
 
 
DISAPPROVED THE ANSWER IF I’M WRONG
