Question

prove that the exterior angle of a regular pentagon is twice the exterior angle of a regular decagon​

Answer 1

Answer:

Each exterior angle of polygon =360/n

Step-by-step explanation:

For a pentagon each exterior angle =360/5=72 degrees

For a decagon each exterior angle =360/10=36 degrees

exterior angle of pentagon / exterior angle of decagon=72/36=2

therefore,

exterior angle of Pentagon = 2 times the exterior angle of Decagon
