A pair of adjacent angles whose non-common sides are opposite rays are called a linear pair. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.
Linear pair
Opposite Rays - are collinear rays having the same endpoint.
Oh honey, an angle formed by opposite rays is a straight angle. It's like a perfectly straight line, no curves or funny business. So if you see those opposite rays coming together, you better believe they're forming a straight angle, no ifs, ands, or buts about it.
opposite rays have common end points

AB and BA.

An opposite ray is a pair of rays that share the same endpoint and extend in opposite directions. This can be visualized as two rays emanating from a common point but extending in opposite directions along the same line.
Not clear what exactly the question is.
Linear pair
If I understand the question: Either pair of opposite angles formed by the intersection of 2 lines.
Because we can't see the image you're referring to, we can't give the answer to which ray is opposite to BA. However, we can help. Opposite rays are two rays that both start from a common point and go off in exactly opposite directions. So, if there are two rays (BA and BC) with a common endpoint (B) going in different directions, they are called opposite rays.
