69
It has 360/60 = 6 sides
If the 135-degree polygon is a regular polygon and each interior angle measures 135 degrees then the polygon is an eight-sided octagon
It will have 360 sides.
If its a regular polygon and each interior angle measures 175.2 degrees then it will have 75 sides
Providing that it's a regular polygon then: 360/15 = 24 sides
15
It is: 360/24 = 15 sides
If it is regular, and all internal angles are 176 deg, then 90 sides.
It will have (1440+360)/180 = 10 sides which is a decagon
There is no such polygon but if you meant an interior angle of 165 then it will have 360/15 = 24 sides
It is: 360/10 = 36 sides
It is: 360/20 = 18 sides
