Answer 1

Two sides of the triangle are marked, this means they are equal to each other. This means this is an isosceles triangle, so two sides are equal.

Meaning that \(\bf{WZ=WX}\).

So \(\bf{2n-5=WX}\).

The perimeter is a total of 20. So you add all the known variables and simplify.

\(\large\bf{(2n-5)+(2n-5)+n=20}\)

Simplify.

5


3


7


6

Answer 3

those are the choices, none of them add up to 20, they're either less than 20 or more than 20

Answer 4

You need to simplify the equation to find what n is.
