Problem
Mišo went on another train adventure – he wanted to cross the entire Africa by train. In the middle of September, before arriving to Nairobi, he saw a reflection of the just-rising Sun in the window on the right while sitting in the direction of the route (facing in this direction). At that time, the train was moving exactly south. 10 minutes later, the train was moving southwest. Determine the angle (in degrees) by which the reflection of the Sun with respect to the wagon deviated from the original position from Mišo's point of view.
