Total angles is 180 x 5 - 360o ie 540o. If the pentagon is regular (all sides equal) then each angle is 108o. If it is not regular then you need the measurement of 4 of the angles.
a seven sided shapes interior = about 128.5 degrees
Each interior angle of a regular 24 sided polygon is 165 degrees
If it is a regular 8 sided octagon then each interior angle is 135 degrees

Exterior angle = 360/20=18 interior angle = 180 - 18 = 162 Must be regular shape
a seven sided shapes interior = about 128.5 degrees
Each interior angle of a regular 24 sided polygon is 165 degrees
If it is a regular 8 sided octagon then each interior angle is 135 degrees
The measure of each interior angle of a fifteen sided regular polygon, a pendedecagon, is 156o.
Providing that it is a regular 15 sided polygon then each interior angle will be 156 degrees
the degrees of a 102 sided shape is 18,000 degrees!
The interior angle of an octdecagon, an 18 sided regular polygon, is 160o.

Exterior angle = 360/20=18 interior angle = 180 - 18 = 162 Must be regular shape
The equation for the size of an interior angle of an n-sided regular polygon is (n-2)180/n. When n=7, the interior angle of a regular sided shape would be 5x180/7 or approximately 128.57. The polygon in the question has an interior right angle (90 degree angle) and thus cannot be a regular shape. A 7 sided shape is called a heptagon. Thus, the shape described in the question is an irregular heptagon.
Providing that it is a regular 38 sided polygon then each interior angle will measure: 170o31'34.74''
The interior angles of an 18 sided polygon add up to 2880 degrees
