In the figure above which of the following must be true?
A. x + y = 180
B. 90 + x = 180 - y
C. 90 + x = y
D. 2x = y
E. 2y = x
I'm confuse and came up with these for each choices and need help on choosing which one is right. Thanks
A. x and y can't be 180 because the center has an 90 degree angle
B. 90 + x should equal to less than 180 right?
C. 90 + x is a large angle that should be bigger than y right?
D. 2x will be bigger then y
E. 2y will be bigger then x
