The length of arc of a circle is a ratio of the total circumference which is 2(pi)r.
Therefore, if the measure of angle x is x, then x/360 = 3/30
This gives x = 36.
Hence, option A > option B.
Therefore, if the measure of angle x is x, then x/360 = 3/30
This gives x = 36.
Hence, option A > option B.
