so the answer is 15°
the circle is 360°
one green angle is 50°
so 4 green angles equals 200°
so 360 minus 200 equals 60.
so 60° angle. and as a result the rest of the angles are 60° of the circle. and so each of the angles are... 15° if the 60 is divided by 4.
Unfortunately you forgot to attach the text, that's why you can't get the answer. I know about which excerpt you are talking about it is " <span>A Hanging (1931)
from Fifty Orwell Essays by George Orwell"</span>, and I suggest you using this option :The execution of the prisoners is viewed as a routine task. Next time check it carefully.
