Find the missing side of the triangle

missing side is √193

= 13.892443989449

Step-by-step explanation:

x (3,7,11,15)

y (4,6,8,10)

A. This IS a function because u have no repeating x values

B. Data in table :

    when x = 11, y = 8

   relation : f(x) = 5x - 21when x = 11

                  f(11) = 5(11) - 21

                  f(11) = 55 - 21

                  f(11) = 34so when x = 11, y = 34

therefore, the relation f(x) = 5x - 21 has a greater value then the table

C. f(x) = 5x - 21f(x) = 99

   99 = 5x - 21

   99 + 21 = 5x

   120 = 5x

   120/5 = x

   24 = x <
