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°
Neither because they are different size and mirrored it could’ve been congruent but it’s double the size and congruent is mirrored and the same size
Answer:
67.5cm^2
Step-by-step explanation:
area of a triangle is 0.5xaxb
Answer:
Just multiply
length x width = area

Step-by-step explanation:
Answer:
Step-by-step explanation:
Let the side length for the octagon having 9m² as area = x
Side length for the octagon having area of 25m² = y.
Thus:
(area of similar polygons theorem)
The scale factor of their sides would be 
. Which is:
Scale factor of their sides =
