    40, 50, and 90

    Step-by-step explanation:

    You know that there are 180 degrees in a triangle, so you'd use the ratio to find each angle by setting up your equation like this: 4x+5x+9x=180

    Then, simplify the equation and solve for x:

    18x=180 x=10

    Then, plug 10 into each x value to find each angle measure:

    4 (10) = 40, 5 (10) = 50, 9 (10) = 90
