Find the measure of arc CD
A) 80 degrees
B) 20 degrees
C) 40 degrees
D) 60 degrees @Mathematics

Answer 1

i think it A!?

Answer 2

I think you're right!

Answer 3

what is the radius?

Answer 4

even if i knew the radius my solution might have been wrong, my method for calculating the arc length doesn't apply to this question anyways, not sure how to solve it :P

Answer 5

AWWW k! :P thankssss!

Answer 6

no it should be A, because the arc length intercepted by a circle doubles if the angle is taken from the circumference as opposed to the midpoint
