Three students are outside looking at the sun during an eclispe (don't worry, they are taking precautions).  Assume the students are the same height.  The three students are collinear but an unknown distance apart.  The first student is able to see the sun tilting up their head at a 30 degree angle.  The second student needs to tilt their head at a 45 degree angle in order to see the sun.  Now though we don't know how far apart the three students are from each other, we do know that second student is perfectly in the middle between the first and third.  What angle must the third student use to see the sun?

the first student used a 30 degree angle and the second student used a 45 degree angle.  The op did not give the third person's angle.

I guess I don't understand. Was that not the question?

maybe i am confused.  but the way i read your solution is that you assumed the first person was 30 degrees, and the third person was 45 degrees and then found the second person.

 

The op gave the first person's angle and the second person's angle and asked for the thirds.
