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.
