No, it isn;t possible.
lets assume the polygon be n-sides.
then
145n=180(n-20)
145n=180n-360
360=180n-145n
360=35n
But n cannot be a fraction, so it isn't possible
it's a heptagon
The interior angles of an octagon add up to 1080 degrees
The interior angles of an 11 sided polygon add up to 1620 degrees
A regular polygon with 4 sides is a square. The measure of any interior angle of a square is 90 degrees.
2340 degrees
No.
No. If the interior angle is 8 degrees then each exterior angle must be 172 degrees. Therefore the polygon must have 360/172 approx 2.1 sides. A fractional side is not possible.
If it's a regular polygon then each interior angle measures 120 degrees.
True, an equilateral triangle has three equal interior angles of 60 degrees.
it's a heptagon
The interior angles of an octagon add up to 1080 degrees
The interior angles of a 16 sided polygon add up to 2520 degrees If it's a regular polygon then each interior angle measures 157.5 degrees
Each interior angle will measure 156 degrees
Each interior angle will measure 162 degrees
If the polygon is regular, the measure of one interior angle of a 24 side polygon is 165 degrees.
No.
