Entering angle value by determining the starting point

Hello everyone,

I have an image of gear and I want to make sure that the angle between the teeth is 9 degrees.
Is there a way to draw one array then entering the angle value to draw the second one?
I know the gear center coordinate

Hi @hadeerashraf2021
Interesting subject: can you drop the image to process? We could test.

What do you mean by :

I mean to draw one array then draw the second one after 8 degrees

I assumed that the gear is perfect, so I measure the inner circle diameter and determined the gear center
So, I need to draw the arrays from this center
