Problem 2.20 | Engineering Mechanics Statics

Hello why do you use phi and not just theta +80

[@ENGMCHANSWERS]

hi there, which angle are you referring to by theta? alpha?

[@alexmurillo8423]

So the final angle being 83.3 why was that the correct direction. I would of thought it was alpha plus 80 so that it would 96.7.
