The sum of the measures of the interior angles in a polygon is 540 degrees. how many sides does the polygon have?

3
4
5
6

If all of the angles add up to 540 then you can divide it by 180 to see how many triangles it contains then from there you know that any polygon has 2 less triangles as it does sides. That means there are 5 sides

2.4+3.2t. you get the answer by adding the ones with variables and ones without

Iagree that is the answer to the question
