Since the value of x was already found to be x = 2, we now can find the perimeter of the triangle.
The perimeter of the triangle is the sum of the measures of its three sides. Since this is a regular triangle, i.e., with all sides with the same lengths, we can find the length of one side, and then multiply the result by 3 to find the perimeter.
The length of each side is 1:
5 - 2x
5 - 2*2
5 - 4
1
Therefore, the perimeter is:
3 * 1 = 3
Answer: 3 units.
