Given triangle \(JLI\) is isosceles with base \(\overline{JI}\), mark the diagram and set up equations using:
\(\angle LJK = 2x + y\) \(\angle LIK = x + 6\)
\(JL = 10x + y\) \(LI = 3y + 12\) \(JI = 7x + 8y + 1\)
Solve your system and find the perimeter of \(\bigtriangleup JLK.\)
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?
