Step-by-step explanation:
We know two sides and the angle between the sides, so we can use the Law of Cosines. Recall that the Law of Cosines states that: 
 , where a and b are the sides and C is the angle in between.
, where a and b are the sides and C is the angle in between. 
Let's substitute 115 for a, 178 for b, and 41 for Angle C. 
Thus: 




 
        
             
        
        
        
A- it’s a Pythagorean triple(6, 8, 10)
