Question

The sum of the interior angles of a convex n-sided polygon can be found using the formula:

Answer 1

360(n – 2)

180(n – 2)

180n – 2

360n

Answer 2

@Mertsj can you help?

Answer 3

Is it a?

Answer 4

consider the triangle (n=3) and sum of interior angles equal to 180.

Answer 5

which of the expressions will be equal to 180 when n = 3?

Answer 6

360(n – 2)??? @sirm3d

Answer 7

replace n by 3 (the number of sides of a triangle) in each expression. the expression that gives 180 (which is the sum of the interior angles of a triangle) will be the correct answer.
