    The measure of the third angle is 100°

    Step-by-step explanation:

    The sum of a triangle is 180 degrees. If the measures of two of the angles is 54 degrees and 26 degrees, what is the measure of the third angle?

    To solve this, we simply need to remember that the sum of angles in a triangle is 180 °

    Let x be the measure of the third angle

    26 ° + 54° + x = 180°

    80 ° + x = 180°

    Subtract 80 from both-side of the equation

    80° - 80° + x = 180° - 80°

    x = 100°

    Therefore the measure of the third angle is 100°
