can anyone do the circled one
plsssssssssssssssssssssssssss
faaaaaaaaaaaaaaaaaaaaaaast

Answer 1

Bonjour!! frnd.

The image is not clear so I can't see whether its 180 or 160.

So , I'll show for both.

Formula for finding sum of interior angles of any polygon is:- (n-2)×180

Here , there are 6 sides; means, n= 6

==> (6-2)×180

==>4×180

==>720

Angles given: 120 , 90 , 110, 130 , 160/180 (image is not clear so I can't see whether its 180 or 160.

So , I'll show for both.) & x

Case 1 - When 160

120 + 90 + 130+ 110 + 160 + x = 720

==> x = 720 - 610

==> x= 110.

Case 2 - When 180

120 + 90 + 130+ 110 + 180 + x = 720

==> x = 720 - 630

==> x = 90
