c. not possible
d. 2π/ 13
e. 5π/ 13

Answer 1

What is (2π - 11π/13) ?

I get 15π/13 , which is not one of your choices.

Do you have a typo?

Answer 2

I get the same answer which is why I originally posted the question - because I thought I was doing something wrong

Answer 3

pi not 2 pi

13 pi/13 - 11 pi/13 = 2 pi/13
so
d

Answer 4

The answer provided by Damon is correct. To be more precise supplement in Geometry means to add to, so Pi is 180 degrees. we need to add 2pi/ 13 in order to be 1 Pi. Therefore the answer is d.
