Answer:
Explanation:
I believe that the answer is 21.3, because if we continue to draw a line between the 2 and the 4, the 4 angles added up would be 360, and angle 2 is 68.7, because 67.3 and 44 added up is 111.3, then 180-111.3 is 68.7, and 68.7 times 2 is 137.4, and 180-137.4 is 42.6, then divide that by two would get us 21.3. Hope this helped! (Sorry if this answer was a bit confusing!)
