Which measure is of an angle that is coterminal with a 95 degree angle

Answers

1). You haven't told us what your choices are, so there's no way
we can help you choose the correct one.

2). An angle that is to be coterminal with another angle of 95 degrees
doesn't need to be any particular size. It just needs to use the same vertex
that the 95-degree one uses.

Edge Answer:

B. 95° – (1,080n)°, for any integer n

Isolate c
a=b(1/c-1/d)
