Answer:
360 degrees
Step-by-step explanation:
Remember that triangles have a sum of 180 degrees, and that quadrilaterals have 360 degrees.
You can either use that part, or actually solve for it.
The equation for the sum of the interior angles is:
[which "n" is the number of sides]
So, if we add in the number of sides to the equation, it changes to:
, which equals to 360 degrees.
