Answer: The value of 'n' is 6.

Step-by-step explanation: Given that ΔXWZ is an isosceles triangle, where XZ = n, WZ = 2n - 5, and the perimeter of the triangle is 20 units.

We are to find the value of 'n'.

As given in the figure, in ΔXWZ,

WX = WZ.

So, WX = 2n - 5.

We know that the perimeter of a triangle is equal to the sum of its three sides, so the perimeter of ΔXWZ is given by

$P=XZ+WX+WZ=n+(2n-5)+(2n-5)=5n-10.$

According to the question, we have

$P=20\\\\\Rightarrow 5n-10=20\\\\\Rightarrow 5n=30\\\\\Rightarrow n = 6.$

Thus, the value of 'n' is 6.

Linear function :The characteristic property of linear functions is that when the input variable is changed, the change in the output is proportional to the change in the input. Linear functions are related to linear equations.
