540 degrees

Sum of interior angles = 180*(n-2)

where n = number of sides of polygon

Exterior angles yes. Interior angles add up to 540.

no.
(x[number of angles in polygon]-2)x180
so 5-2)x180=3x180=540
the number of degrees?
540.

all fully enclosed shapes must have a total of 360 degrees when the sum of all angles is reached.
