Wait. I think you are wrong. < Think. Exterior means the outside angle. Where did you get the extra line for A from? I think I am missing something. I believe it is 310 degrees because angle B is 40 degrees and angle C is 90 which makes angle A (inside angle) 50 degrees. At a single point, the angle must be 360 all around so 360-50 = 310. i am positive it is 310 degrees or something is not right here.
