    sorry, we cannot help you since the diagrams you have provided don't specify which angles we are looking for, that is what janvid is trying to say.
    ie. you say 100 degrees but WHICH angle is 100 degrees? you just write it in open space, please put the text inside an angle, that will help greatly thank you.

    The angle 3 intersects to arcs: 150deg & 100deg.
    The difference is 50deg. Therefore, angle 3 is 25deg.

    problem 1 has also some information missing. You have to know the measure of another arc (let's say y) to be able to determine the angle 1.
