The mean of five numbers is 15. four of the numbers are 3,19,8, and 32 whats the fifth number

Setup Average Equation:

Average=Sum of our 4 numbers + unknown number of x
               
                                          Total Numbers
15 = 3 + 19 + 8 + 32 + x
       
                      5
Cross Multiply

3 + 19 + 8 + 32 +  = 15 x 5
x + 62 = 75
Subtract 62 from both sides of the equation to isolate x:

x + 62 - 62 = 75 - 62
x = 13          

You need to include the original coordinates of the triangle to answer this. and how much does it translate (move left right up down)
