Given triangle JLI is isosceles with base ¯JI, mark the diagram and set up equations using:
∠LJK=2x+y ∠LIK=x+6
JL=10x+y LI=3y+12 JI=7x+8y+1
Solve your system and find the perimeter of △JLK.
find x, y, and the perimeter.
Where is K located?
Do you have a picture? I mean, you don't need a pic, but where is K?
