interior angle + exterior angle =180 degree
So, other interior angle = 180-100 =80 degree
So, other interior angle = 180-100 =80 degree

Answer
140°
Step-by-step explanation:
Sum of all interior angles of an octagon :-
= (2n-4)×90
= (2(8)-4)×90
= (16-4)×90
= 12×90
= 1080°
Measure of other angles :-
100°+x+x+x+x+x+x+x = 1080°
100°+7x = 1080°
7x = 1080-100
7x = 980
x =
x = 140°
