Answer:
180×(n−2)
Step-by-step explanation:
To find the sum of the interior angles of a polygon, you typically use the formula:
Sum of interior angles

∘
Sum of interior angles=(n−2)×180
∘
where
n is the number of sides (or triangles, in this case) of the polygo
Since the regular polygon is decomposed into
n triangles, the number of sides of the polygon will be
n. So, the correct expression representing the sum of the interior angles of the polygon is:
