This one works out OK if you do the math first and then figure out what type of mirror it must be. You know ho, do, hi. Keep track of that. Now we know di and do, so we can get the focal length. Once we know those angles, we can figure out the length the ray travels.
First step is to determine the incident angle.
We know one triangle with an opposite side of 1.3 m, and an adjacent side of 2.7 m. This makes the angle 26 . So we actually need the complementary angle of 64 . Now we use Snell's law to figure out what angle the light is at in the water. This equation gives us a refracted angle of 42 .
