At a swim meet, a parent is videotaping his son from a seat in the stands that is 20 meters past the starting line and 8 meters away from his son's lane. Let x represent the distance the son has swum.
a. Write x as a function of (theta).
b. At what angle does the parent have the camera when the race is just starting?
c. At what angle does the parent have the camera when the son has swum 25 meters.
Student note: There is a diagram with the question. I do not know if that matters too much, I do not think it will. I am very confused as to how I am supposed to set up an equation. And for part A. I just want to say that x is only part of the less than 20 meters
