Answer:
Rev. Parris was so fearful that the villagers will discover his niece and daughter were amond the girls dancing in the woods because, in the village, it was part of the rituals of witches to dance around fire in the forest.
As a reverend who had already made enemies that wanted to see him fail and fall, this information would be a great instrument in their hands because he would be labelled a hypocrite, a reverend whose family practiced witchcraft and yet he preached against it.

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.
