Step-by-step explanation:
Given:
Required:
LJ
Solution:
Step 1: create an equation to find the value of x
Since we are given that LK = MK, and LK = 7x - 10, let's find the expression for MK to get an equation.
(segment addition postulate)
(Subtract KN from each side)
(subtitution)
LK = MK, therefore,
Subtract 8x from each side
Add 10 to both sides of the equation
Divide both sides by -1
Step 2: Find LJ
(segment addition postulate)
Plug in the value of x
