Question

Find the sum of angle a,b,c,d and e in a star

Answer 1

Answer:

Step-by-step explanation:

Proof for any star pentagon

Thus the top triangle has angles a, b + d, and c + e: Since the sum of the angles in a triangle is 180 degrees, and this triangle has the sum of all the corner angles, we are done! There are many other ways to prove the result too!

Answer 2

Answer:

the answer is 180 according to 360 by 5 equal to 72 then we get something like 180
