The answer is B. :PPPPPPPPPP
I would but I don’t know how to explain it all!
The sum of the angles in a pentagon is 540°.
This means that each angle is 108°.
Inside you pentagon, a triangle is drawn. This triangle is isosceles, because the corners are on the points of the regular pentagon. You know that angle C is 108°.
Angles in a triangle add up to 180°.
B and D will be the same size as this is isosceles.
180°-108° = 72°
This is B and D. You only need one of these, so you divide by 2.
The answer is 36°.
Hope this helps :)
Answer:
It moved because of this:
Step-by-step explanation:
the number 10 has one 0 in it.

hope this helped!
