    The largest angle is 90 degrees

    Step-by-step explanation:

    The three angles of a triangle add to 180

    The ratio is 10 : 3: 7

    Multiply each by x

    10x, 3x 7x

    Add them together and set equal to 180

    10x+3x+7x = 180

    Combine like terms

    20x = 180

    Divide by 20

    20x/20x = 180/20

    x = 9

    The largest angle is 10x

    10*9 = 90

    The largest angle is 90 degrees
