    Answer:

    130^{\circ}

    Step-by-step explanation:

    A straight line can denote half a circle, each side having 180^{\circ}. Therefore, the sum of these three angles should be 180^{\circ}. Since the first two angles both measure 25^{\circ}, we can set up the following equation and solve:

    25+25+m\angle 3=180,\\m\angle 3= \fbox{$130^{\circ}$}.
