Question

Find the sum of the measures of the interior angles of the polygon below.

Answer 1

you have a pentagon

the formula for angle sum is

\[Sum =(n -2) \times 180\]

where n = the number of sides

substitute n = 5 and calculate

Answer 2

540 degrees

Answer 3

S = 180(n-2)

S = 180(5-2) .... plug in n = 5 (there are 5 sides)

S = 180*3

S = 540

So the angles in a pentagon add up to 540 degrees
