## Emily778 2 years ago Find the measure of angle BAC.

It will be 1/2 of the angle that's listed at the center. So: 57/2 = 28.5 degrees

The supplement of angle AOB which is 66 degrees (AOC) is 114 degrees. 114/2 = 57 degrees

5. Emily778

Thanks. :) one more?

6. Emily778

m<R=22 degrees. Find m<O.

22x2=44 degrees

THANKYOU SO MUCH

10. Emily778

Can you help me on 5 more? :D

11. FutureMathProfessor

Is it getting easier? :D Just know that the angle from the center will be twice the angle from the other side

1.) m<S=36 degrees, mRS=118 degrees, and RU is tangent to the circle at R. Find m<U.

13. Emily778

Lol. I dunno, you tell me. :D

14. Emily778

2.) mDE=128 degrees and mBC= 63 degrees. Find m<4
