Answer:
   √7 ≈ 2.646
Step-by-step explanation:
The law of cosines is applicable. It tells you ...
   c² = a² + b² - 2ab·cos(C) . . . . . where a, b, c are triangle side lengths, and angle C is opposite side c.
Filling in the given information, you have ...
   c² = 2² + 3² - 2·2·3·cos(60°) = 4 + 9 - 12·(1/2) = 7
   c = √7 ≈ 2.646
The length of the third side is √7, about 2.646 units.
 
        
                    
             
        
        
        
(-2.3)*4.7 would be equal to -10.81
