Question

10.

10. The sum of the interior angles of a polygon is 2,340°
How many sides does the polygon have?
I
11
11. What is the measure of each interior angle of a
regular pentagon?
12. The exterior angles of any polygon add to
12

Answer 1

Explanation:

10. To solve for this, use the formula: 180*(n-2)

So, 180(n-2) = 2,340

Once n is solved for, that is the number of sides

11. Use the formula:

[180*(n-2)]/n

(n represents the number of sides)

12. Think of the sum of all interior angles in a quadrilateral
