Answer 5

Good.
A pentagon has 5 sides.
There is a formula that tells you the sum of the measures of the angles of any polygon if you know how many sides it has.

Here is the formula:

sum of the measures of the angles of a polygon = (n - 2)180

n = number of sides.

You have a pentagon with 5 sides, so n = 5.

Replace n with 5 in the formula.
What do you get for the sum of the measures of the angles of the pentagon?
