    Answer: the measure of the third triangle is 75 degrees.

    Step-by-step explanation:

    Let the measure of the third angle be x degrees.

    The sum of the three angles in a triangle is 180 degrees.

    One of the angle measures 30 degrees, and the second angle measures 75 degrees. Therefore,

    30 + 75 + x = 180

    105 + x = 180

    Subtracting 105 from the left hand side and the right hand side of the equation, it becomes

    x = 180 - 105 = 75 degrees
