i solved for the correct answer, and got a negative angle, so i added 360 degrees to it to get a positive value. the answer formats are not clear enough to show that negative results are acceptable. also the figure couldnt exist(as depicted in the problem,the lines would need to be switched and the connecting line in opposite direction) with that angle.
