    State the quadrant of the angle x and find the value of the basic angle a if
    (a) x = to 25°

    (b) x = -100°

    b) is in quadrant 3 and the basic angle is 260

    depends if your taling about sine ,cosine or tan. If we were talking about tan 80 would be the basic angle.

    If the angle is in standard position,
    a) Quadrant I
    b) Quadrant III

    I tried to draw a little ascii picture but it would have just confused you.
