Hello everyone. I was hinted by a member that I should use pythagoris and some trig to figure the length out. It all made sense but now I'm not getting the right answer and I'm wondering if its becuase I assumed the first triangle had a length of 3.10, because it said the bird is 3.10m from the mirror, is that info just useless and they wanted me to use the information of the 2 other sides, 4.10 and 4.90 and find the ohter side? 4.90^2 = 4.10^2 + b^2?
Here is the problem and my drawing:
You look through a camera toward an image of a hummingbird in a plane mirror. The camera is 4.30 m in front of the mirror. The bird is at camera level, 4.90 m to your right and 3.10 m from the mirror. What is the distance between the camera and the apparent position of the bird's image in the mirror?

I also asked my professor and he said yeah this is how u do it, which isn't right.
