    x=45

    Step-by-step explanation:

    Okay then. In a triangle, the all three angle values combined equals to 180 degrees. So 24+30 + (3x-9) = 180. Then, you can solve for x.

    24+30 + (3x-9) = 180 Equation

    45+3x=180 Combine like terms

    3x=135 Subtract 45 from both sides

    x=45 Divide both sides by 3
