Answer:
5.6
Step-by-step explanation:
Use pythag to get SU. 10^2 + x^2 = 15^2, this will give you x = 11.2. 11.2 is the diameter of SU so divide it by 2 to get the radius. 11.2/2= 5.6.
 
        
             
        
        
        
I think the answer would be 1.8
        
             
        
        
        
The system of equations has infinite solutions.
<h2>Given to us,</h2>
<h3>Equation 2,</h3>
The value of y is already given in equation 1,

substituting the value of y in equation 2,

The solution of the two equations is 0. Also, we can see that both the equations are in ratio. 
Further, the image also shows that the line of the two equations are coinciding.
Hence, the system of equations has infinite solutions.
