Step by step: GR-8 = 34x - 12 • move variable to left hand side -34x + gr -8 = - 12 • change expression and move to right side -34x = - 12 - gr - 8 • calculate sum -34x = - 4 - gr • divide both sides X = 2/17 + 1/34gr And there’s your answer :)
Please graph the triangle using the info in the description provided. The answer to this question will likely become self-evident if your drawing is correct. Remember, the sum of the 3 interior angles of any triangle is always 180 degrees.
