  • Angles in a triangle always add up to 180, so you could write an equation to solve for x:
    31 + x + 4 + 3x + 9 = 180
    44 + 4x = 180
    - 44
    4x = 136
    ÷ 4
    x = 34
    So now that you have the value of x, you can use substitution to find angles S and T.
    34 + 4 = 38° = angle S
    34 × 3 = 102
    102 + 9 = 111° = angle T

    I hope this helps!
