Equilateral Geometry Question

  1. Feb 21, 2012 #1
    1. The problem statement, all variables and given/known data
    Th measure of the sides of an equilateral triangle are represented by x + 12, 3x - 8, and 2x + 2. What is the measure of each side of the triangle.



    2. Relevant equations



    3. The attempt at a solution
    Well, I know that each side of this triangle are equal, resulting in only one x-value. I first thought of solving them as a system of equations, but then I realized that these are just expressions--they are equal to nothing. How do I solve this?

    If A, B and C are the lengths of the side of an equilateral triangle then A=B=C.

    Putting two sides equal to each other should give you the desired result.
