An astronomer knows the distances from herself to stars A and B as well as the distance between them.

The distances are 450, 400, and 90 light years (1.y.) respectively.

If the astronomer's telescope is currently pointed at star A. how many degrees must she rotate her

telescope to see star B?

Do not round during your calculations. Round your final answer to the nearest degree,
