Answer:

CR = 53(I will not be explaining that one as it shows the answer in the picture)

AB = 109˚

CAB = 236˚

Explanation:

To find CAB, you will need to add 53˚ and 71˚. The sum is 124˚. Every circle is 360˚, so subtract 360˚ by 124˚.

360 - 124 = 236˚

Therefore CAB is 236˚, due to the fact that CAB is the only arc left when you take the others out.

To find AB, you will be focusing on that specific half, and half of 360˚ is 180˚. Since RB is 71˚, you have to subtract 180˚ by 71˚ since AB is the remainder of the half.

180 - 71 = 109˚

Therefore AB is 109˚.
