Question

3. What is the value of x in the regular polygon below?

Answer 1

options are 40, 120, 60, and 150

Answer 2

This is a hexagon, so the measure of each interior angle is 180(6-2)/6 = 120 degrees.

So solve 3x = 120 for x to get your answer.

Answer 3

so its 40

Answer 4

yep

Answer 5

ah! thank you so would that mean the exterior is 60?

Answer 6

exterior = 180 - interior

exterior = 180 - 120

exterior = 60

so yes

Answer 7

Thank you soo much!

Answer 8

or...

exterior = 360/n

exterior = 360/6

exterior = 60

Answer 9

So applying that to an octogon the exterior would be 45 right?
