    A triangle's angles sum to 180 degrees.

    7x + x + 6 + 2x + 4 = 180

    10x + 10 = 180

    10x = 170

    x = 17

    1st angle = 7(17) = 119

    2nd angle = 17 + 6 = 23

    3rd angle = 2(17) + 4 = 38

    Good question.

    Anyway, you know that within any triangle, all of the interior angles equals 180 degrees.

    The question gives you the three interior angles.

    that means, 7x+(x+6)+(2x+4) = 180

    simplifies to 10x+10 = 180

    10x = 170

    x = 17

    Then we put this x value into the equations for each of the angles.

    7(17) = 119

    (17)+6 = 23

    2(17)+4 = 38

    Therefore, the three angles are 119, 23, 38.

    7x+x+6+2x+4= 180 degrees (triangle)

    combind the like terms

    7x+x+2x= 10x 6+4= 1=

    10x+10=180

    subtract 10 from both sides

    10x=170

    divide 170 by 10

    x=17

    now you plug in

    side 1= 7 times 17= 119

    side 2= 17+6= 23

    side 3= 17 times 2 +4= 38
