An irregular polygon has its exterior angles as 140,120,142,132,112 n x degrees Find the value of x.

4 answers

Assuming that by "n" you mean "and" then there are 6 angles, and their sum is

4*180 = 720

So, add 'em up and see what x has to be to make 720.

x=74

What does x has to be to make 720

Where from the 4
