Answer:
155°
Step-by-step explanation:
We know that the sum of the sections must be 360°. So, by removing a section of 75° he leaves the paper circle with a section of 185°, then removes another 130° section, leaving the last section of 155°.
Answer:
BC = 9 miles
Step-by-step explanation:
Here, we are given ΔABC ∼ ΔEDC, which means both triangles are similar and they tend to have the same dimensions and properties.
To find the length of BC, we are given the proportion:

Where x represents the length BC.
Solving further, let's cross multiply


Solving for x, we have:

Lets divide both sides by 8


Therefore the distance BC is 9 miles
The first week is 10 x 1.4.
The second week is that answer x 1.4 etc.
So you are only multiplying the first week by 10.
{ [ 10 x 1.4) x 1.4] x 1.4}. Since multiplication is commutative, we don’t need the grouping symbols...
10 x 1.4 x 1.4 x 1.4
That s answer A
