Question

the sum of all interior angle of a regular polygon is 1080.what is the measure of each interior angle?

Answer 1

Sum of interior angle=(no. of angles-2)×180=1080.
no.of angles=(1080÷180)+2=8
one angle measure =1080÷8=135

Answer 2

Step-by-step explanation:

here is your answer ✌️✌️✌️....

each exterior angle= ( 180- 1080/n ) °

180 - 1080/n = 360/n

n = 8

each interior angle= 1080/n = 135 °

I hope you understand ☺️☺️☺️☺️.....
