80 and 150 degrees
Work Step by Step
We know that the sum of the interior angles is given by: Sum=180∗(n−2) Where n is the number of sides. Thus, for the given problem, we have: Sum=180∗(4−2) =360 Since the sum of the interior angles must be 360, we find that the remaining angles must add to: 360-80-50=230. Thus, 80 and 150 degrees is the only possible answer among the options given.
