Answer: x = 35 (choice D)</h3>
====================================================
Work Shown:
secant angle = (far arc - near arc)/2
angle BGC = (arc BC - arc AD)/2
40 = (115 - x)/2
2*40 = 115-x
80 = 115-x
115-x = 80
-x = 80-115
-x = -35
x = 35
For more information, you can search out "secant angles" and it should go over how the formula is set up and why it works.
Let's assume that the statement "if n^2 is odd, then is odd" is false. That would mean "n^2 is odd" leads to "n is even"
Suppose n is even. That means n = 2k where k is any integer.
Square both sides
n = 2k
n^2 = (2k)^2
n^2 = 4k^2
n^2 = 2*(2k^2)
The expression 2(2k^2) is in the form 2m where m is an integer (m = 2k^2) which shows us that n^2 is also even.
So this contradicts the initial statement which forces n to be odd.
