Set A is the set of factor 12, set b is the set of even natural numbers less than 13, set c is the set of odd natural numbers less than 13, set d is the set of even natural numbers than 7. The universal set is the set of natural numbers less than 13

i got 10.28 but that rounds up to 10.3

ca = ec

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches
