1. remember all of them add up equal to 360 degree.
2. add all of them up together
3. combine like term then solve for Y
4. you will figure the arc measure of BC when you get answer for Y.
or you can turn it like this...
Ok so whit the data that we got we can proceed like this:
[(-2, 7), (1, 0)]
d = 2/3
Now lets find the difference between x and y terms.
The difference of -2 and 1 is 3,
The difference of 7 and 0 is 7.
x = 3
y = 7
Now Multiply it by two thirds.
2/3 * 3 = 2
2/3 * 7 = 4.7
So the answer is the second option. Hope this helps

If you are multiplying by 100, the decimal will move 2 places to the right.
It moves to the right when multiplying because the number is getting greater, and there are 2 zeroes in 100 so it moves twice.
