I don't understand how to do it! Please, help! :)

**drwls**, Thursday, January 29, 2009 at 1:25amBecause the two triangles are congruent, the following pairs of side lengths are equal: JK = MN, KL = NP and LJ = PM

The last two relationships tell you that

21x - 2 = 20x, and 15x = 13x + 4

Both of those equations tell you that x = 2. (The gave you more information than you need to solve the problem!)

Since x = 2, LJ = 4
