Answer:
yes they are proportional
bearing in mind that arcs get their angle measurement from the central angle they're in.
since point C is the center of the circle, then ∡ACB is a central angle, containing the arcAB, and since arcAB = 36° = ∡ACB.
The answer is C.......Sports Stamps = 4 , Holiday Stamps = 2 , Presidents Stamps = 8. He said 4 times as many presidents than holiday. So the number of presidents stamps is the product of the holiday stamps times 4. 4 times 2 is 8. Add them all together
This in what I got:
(-7i)(10i)
-70i
