Question

1. find jl.

j 6x + 12 k 9x + 5 l
5x + 57

Explanation:

Step1: Set up equation for JL

$JK + KL = JL$
$(6x + 12) + (9x + 5) = 5x + 57$

Step2: Simplify left side

$15x + 17 = 5x + 57$

Step3: Solve for x

$10x = 40 \implies x = 4$

Step4: Calculate JL

$JL = 5x + 57 = 5(4) + 57 = 77$

Answer:

77
