Include Picture of triangle
Few things about the solution -
Should we manually come up with the equation of the line in solution 1 or maybe in the hint? I'm not sure how well covered linearization is in this course.
Second I don't know if trig is meant to be a stumbling block in this question but perhaps a relevant picture of the special triangle would be nice. Otherwise some of these values just seem to appear from nowhere.
