I believe it is 4/12 since you have a total of 12 marbles and only 4 are red plastic ones
The common endpoint is Q. The angle is: angle RQP, angle PQR, or just angle Q

If that makes any sense ♀️
The answer to your problem is 50b+8
The answer
let p' be the corresponding angle of the angle p (that is because of the prallelism and the transversal, look the image)
but p' and p are correspondant angles implies p'=p,
looking at the figure, p' and q are opposite angles
so q=p' and p'=p implies q=p
the answer is
<span>p = q</span>
