Question

jkl is isosceles with kl= lj. jl is five less than two times a number. jk is three more than the number, kl is one less than the number. find the measure of each side

Answer 1

JL= 3

JK =7

KL = 3

Explanation:

Let the number be x.

JL = 2X - 5

JK = X +3

KL = X - 1

KL = LJ

X-1 = 2X-5

2X - X = -1 + 5

X = 4

JL = 2X - 5 = 2*4 - 5 = 8-5 = 3

JK = X +3 = 4 + 3 =7

KL = X - 1 = 4 -1 = 3
