Question 936581
since it's an equilateral triangle, the sides are equal to each other.


this means that x = 5x-2


subtract x from both sides of this equation and add 2 to both sides of this equation to get:


4x = 2


divide both sides of this equation to get:


x = 2/4


each side is equal to 2/4


the perimeter is equal to 6/4 = 3/2.
