I believe you meant:  Use completing the square to determine the center and radius of the circle represented by this equation:   <span>X^2+y^2-10x+6y=15
x^2 - 10x + 25 - 25 + y^2 + 6y + 9 - 9 = 15
Then:
     (x-5)^2               +   (y+3)^2            = 24   = 2sqrt(6)
This circle is centered at (5,-3) and has radius 2sqrt(6).</span>

Answer:
Step-by-step explanation:
LHS = Sin² ∅ + Sin² ∅*tan² ∅
         = Sin² ∅ [1 + tan² ∅ ]                 {Sec² ∅ - tan² ∅  = 1}
          = Sin² ∅ *Sec² ∅ 
          = Sin² ∅ * 
          = Sin² ∅ /Cos² ∅ 
         =  tan² ∅  = RHS
 
        
                    
             
        
        
        
If there were 37 apples. One of your friends took 5 apples. You divided the leftover apples and gave it to your four friends. How many apples did each of the four friends get?
x=8
37-5=32
32/4=8.
