I think it is dividing the numbers by 2
I know... It's hard to study for quiz, test, and more right? In the end there is a * meaning that it is a question on google forms. I'll help you out though. DO NOT do this next time okay? :)
Step-by-step explanation:
Answer:
C and D
Step-by-step explanation:
CommentThe measurement of an arc in degrees is the same as the central angle. We must assume that the central angle is the measurement given.

= 49
To find the next one you need to find the measurement from B to C, the arc that is over 180 degrees. Maybe you could put another letter between B and C so that we could refer to that top arc greater than 180 degrees. Call the point you inserted D.

= 360 - 49 - 107 = 204

=

+
Arc(
ABC) = 204 + 49 = 253
Arc(
BAC) = Arc(BC) + Arc(AB)
Arc(
BAC) = 107 + 49
Arc(
BAC) = 156
Arc(
ACB) = 107 + 204 = 311
Answer: 10
Step-by-step explanation:
use a^2 + b^2 = c^2
where a = |y2 - y1| = 11 - 3 = 8
where b = |x2 - x1| = |-2 - 4| = |-6| = 6
8^2 + 6^2 = c^2
100^2 = c^2
c = 10
