  1. Don't know what else I can do

    just translate into Math

    smallest angle --- x°
    "One angle in a triangle has a measure that is three times as large as the smallest angle. "
    second angle = 3x
    " the third angle is 10 degrees more than that of the smallest angle"
    third angle = x+10

    x + 3x + x+10 = 180
    5x = 170
    x = 34

    smallest angle , we called it x, so 34°
    second angle, we called it 3x, so 102°
    third angle, we called it x=10, so 44°

    check: do they add up to 180 ?
    34+102+44 = 180
