This question is weird. what does the 2nd bird has anything to do at all.  since the question only involves the first bird and the bird watcher.

No wonder. without the diagram this would be unsolvable.

cos x = adj/hyp
cos x = 17.8/37.4= 0.475935829
then just cos^-1 (0.476) = 61.6 degrees approx.
