Answer:
(7,12),(-12,-7)
Step-by-step explanation:
x^2 + y^2 = 193
x - y = - 5
x = y - 5
(y - 5)^2 + y^2 = 193
y^2 - 10y + 25 + y^2 = 193
2y^2 - 10y + 25 = 193
2y^2 - 10y + 25 - 193 = 0
2y^2 - 10y - 168 = 0 
2*(y^2 - 5y - 84) = 0     This factors into 
2*( y - 12) (y + 7) = 0
y = 12    
in which case x = 12 - 5 = 7
y = - 7
in which case x = -7 - 5 = - 12
 
        
             
        
        
        
Answer:
the answer is C 
Step-by-step explanation:
 
        
             
        
        
        
X=8.5
190-5=185
185/-5=-37
-37-3=-34
34/4=8.5
        
             
        
        
        
<span>Angle T = Angle C, let them equal x 
So x + x + 140 = 180 
2x = 40 
x = 20 
So Angle T = 20 degrees </span>
