Answer:120°
Step-by-step explanation:
Given
cake is cut into 12 equal pieces
We know the top view of cake is similar to circle .
So, if a circle is divided into 12 equal parts then
each part subtend an angle of
∅ = 360/12 = 30%
If 8 slices were eaten , then 4 slices are remaining
These 4 slices measure subtend equal angle at the center therefore
4 slice measure a total of 4 × ∅
➡️ 4 x 30°
➡️ 120°
A) 4 (3x+2)-2
12x+8-2
12x+6
2x+1 simplified expression
Answer:
a = 150
Step-by-step explanation:
The sum of the internal angles of an octagon is 1080°.
(There are four 
and 4 
, they sum to 1080°)
Hope this helps :)
