2400 and 1200 would be my estimates.
Answer:
AC ≈ 2.18
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan70° =
=
= 
Multiply both sides by AC
AC × tan70° = 6 ( divide both sides by tan70° )
AC =
≈ 2.18 ( to the nearest hundredth )
Yes it is the same except there are two arcs you need to find the length for in this one.

which means

which in turn means the next two terms are

and

.
Answer:
No
Explanation:
The independent irrelevant alternative criterion is not violated here. The law of irrelevant alternative criterion holds that if candidate A is liked more than candidate B then a new candidate C who is liked less than candidate A should not spoil the victory of Candidate A, so that candidate B wins.
In the example in the question, candidate Parker was the preferred candidate before the elimination of candidate Myers and so will still be the winner of the election, therefore the irrelevant alternative criterion has not been violated.
