Answer:
x = 6; measure of each side 83
Step-by-step explanation:
Equilateral Triangle means all sides are equal length
Knowing this, you can set up the following equation:
2(JK/KL/JL) = 2(JK/KL/JL) <all lines are interchangeable in the equation as long as they are not the same on both sides>
2(13x+5) = 2(17x-19)
26x+10 = 34x-38
x = 6
Plug in the variable:
13(6) + 5 = 83
17(6) - 19 = 83
8(6) + 35 = 83
