Providing that it is a 13 regular polygon each interior angle will be 152.3076923 degrees.

The interior angles add up to 1980 degrees.

The measure of each interior angle of a dodecagon, which is a 12 sided regular polygon, is 150o. This is found in any polygon by multiplying 2 less than the number of sides by 180o and then dividing the product by the number of sides. A dodecagon interior angle is then 10 x 180o/12 = 150o.

Im stuck on that too :/

A 16 sided polygon

With a protractor or if you know the exterior angle then it's 180 - exterior angle = interior angle

If its a regular polygon then 180-interior angle and divide the answer into 360 which will give the number of sides of the polygon.

The interior angle of an octdecagon, an 18 sided regular polygon, is 160o.

It is: 180-exterior angle = interior angle because there are 180 degrees on a straight line
