Answer:

The length of side JK  is 4.7 units.

Step-by-step explanation:

Given:

Δ JKL is an Isosceles Triangle.

JL = 5x - 0.2

KL = x + 3.2

JK = 4x - 1.3

To Find:

The length of side JK = ?

Solution:

Δ JKL is an Isosceles Triangle. ......Given

JK = KL  .........................Given

Substituting the given values we get

[tex]4x-1.3=x+3.2\\\\4x-x=3.2+1.3\\\\3x=4.5\\\\x=\frac{4.5}{3} \\\\x=1.5[/tex]

Now substituting 'x' in JK we get

[tex]l(JK)=4(1.5)-1.3\\\\\therefore l(JK)=4.7\ units[/tex]

The length of side JK  is 4.7 units.
