by counting them?
That will depend on how many sides the polygon has.
There is no formula for how many sides there are in a polygon; the name of the polygon shows how many sides it has.
add the sides of the polygon.
It will have 12 sides
how many diagonals are there iin a polygon of 11 sides

If the only information that you have is the angle and the shape is a polygon, then you cannot determine how many sides the polygon consists of. The minimum number of sides is 3, but without seeing a picture, or knowing what type of polygon (e.g. right triangle or equalaterial triangle), then you won't be able to determine how many sides the polygon has.
add the sides of the polygon.
There are 8 sides in the polygon with 8 sides (an octagon).
It will have 12 sides
I do not no how about you find out what a polygon is then count the sides -A
how many diagonals are there iin a polygon of 11 sides
Polygon means "many sides."
A polygon has as many angles as sides, so a polygon with 10 sides (decagon) would have 10 angles.
A polygon must have at least three sides.
an octagon is a polygon. an octagon has 8 sides. a polygon is a shape with closed sides.
