Answer:
160
Step-by-step explanation:
5x-10+12x=16x
17x-16x=10
x= 10
exterior angle at C = 16x= 16×10 = 160°
 
        
                    
             
        
        
        
X₁ + X₂ / 2   & Y₁ + Y₂ / 2 ------------- This is the formula to plug in the coordinates. 
3.5 + 1.5 / 2= 2.5      2.2 + (-4.8) / 2= -1.3
Answer = (2.5,-1.3)
