One doesn't have to be at any specific angle to see a rainbow. What is Dependent on seeing the rainbow is the location of the rain, and sun relative to you. The sun is always behind a rainbow when seen. So you would be in front of the rainbow, rain, and the sun. Also, No two people see the same rainbow unless a picture or video was taken of the rainbow.
