Consider the figure.<br> What is JL?
lisov135 [29]

The answer for the above mentioned problem is JL = 12.5

Step by step explanation:

Given:

JM = 8

KM = 6

To Find:

JL = ?

Formula to be used:

KM^2 = JM x ML

In order to find " JL" we must first find "ML",

KM^2 = JM x ML

         6^2 = 8 x ML

         36 = 8 x ML

         36/8 = ML

         ML = 4.5

Now JL = 4.5+8

             = 12.5

Thus the value of JL = 12.5
