Answer:

  3)  74°

  4)  260°

Step-by-step explanation:

3) Angle CAE is vertical to angle FAB, which is shown as 121°. Vertical angles are congruent. So, we have ...

  ∠DAE +∠DAC = ∠EAC

  ∠DAE + 47° = 121° . . . . . . . fill in known values

  ∠DAE = 121° -47° . . . . . . . . subtract 47°

  ∠DAE = 74°

__

4) arc MJL is the long arc that completes the circle along with short arc MJ. Short arc MJ has the same measure as its central angle, 100°. Then long arc MJL is 360° -100° = 260°.

  arc MJL = 260°
