Question

how many side does a regular polygon have if each of its interior Angel is 150degree

Answer 1

Answer:

Hello mate,

Step-by-step explanation:

Since an interior angle is 150 degrees,

its adjacent exterior angle is 30 degrees.

Exterior angles of any polygon always add up to 360 degrees.

With the polygon being regular,

we can just divide 360 by 30 to get 12 sides.

Hope the above helps
