The length of the sides of any right triangle are always less than the length of the hypotenuse. The sine and cosine functions find the ratio between a side and the hypotenuse, so it's always less than 1.
5 times 100 = 500
500 divided by 20 = 25

Since the only places where an x-ordinate exist are the closed circles, the domain will simply be:
D: { -5, -4, -3, 1, 2, 5 }
X and 67° are supplementary (they equal 180) so to find x you do 180-67 which equals 113. So x=113°
