I think it will take 45 minutes because 30/2 = 15 and 60/2 = 30.
So, 30 + 15 = 45

30+60/2
= 90/2
= 45 mins

Find the measure of each<br>exterior angle of regular polygonof a 9sides.<br>

Ronch [10]

Answer:

40

Step-by-step explanation:

Any regular polygon has exterior angles = to 360 / number of sides.

so a 9-gon has 9 sides. The exterior angle = 360 / 9 = 40

Each exterior angle will be 40 degrees.

Try it with simpler n-gons. A triangle has 3 sides. The exterior angle is 360 / 3 = 120

A square has 4 sides. Each exterior angle is 360 / 4 = 90
