    Answer: 20°

    Step-by-step explanation:

    Hi, to answer this question we have to analyze the information given:

    Angle 1 = 55°

    Angle 2 = 105°

    The sum of the three interior angles of a triangle is always 180°.

    So:

    180 = 55+105 + x

    Where x is the missing angle.

    Solving for x:

    180-55-105 = x

    20°=x

    Feel free to ask for more if needed or if you did not understand something.
