Use the diagram to find the measure of arc. AB and CD and the diameters of the circle F

11). = 90°

12). = 212°  

Step-by-step explanation:

A circle F with AB and CD are the diameters has been given in the figure attached.

11). Since, = 180°

    and

    Therefore, = 180°

    32° + + 58° = 180°

    = 180° - 90°

                = 90°

12. Since, = 32°

                  =

                                = 180° + 32°

                                = 212°
