Answer :
The probability that the coin will land on an area that is white is ![\dfrac{1}{2}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B2%7D)
Explanation :
Given that,
A 7-by-7 foot rug is shown in figure.
Suppose, all parts are equal.
The area of rug is
![A_{r}=7\times7](https://tex.z-dn.net/?f=A_%7Br%7D%3D7%5Ctimes7)
Area of one part of rug is
![A'_{1}=3.5\times3.5](https://tex.z-dn.net/?f=A%27_%7B1%7D%3D3.5%5Ctimes3.5)
We need to calculate the probability that the coin will land on an area that is white
Using formula of probability
![P=\dfrac{Area\of\ white\ part}{Area\of\ total\ rug}](https://tex.z-dn.net/?f=P%3D%5Cdfrac%7BArea%5Cof%5C%20white%5C%20part%7D%7BArea%5Cof%5C%20total%5C%20rug%7D)
Put the value into the formula
![P=\dfrac{(3.5\times3.5)+(3.5\times3.5)}{7\times7}](https://tex.z-dn.net/?f=P%3D%5Cdfrac%7B%283.5%5Ctimes3.5%29%2B%283.5%5Ctimes3.5%29%7D%7B7%5Ctimes7%7D)
![P=\dfrac{2\times3.5\times3.5}{7\times7}](https://tex.z-dn.net/?f=P%3D%5Cdfrac%7B2%5Ctimes3.5%5Ctimes3.5%7D%7B7%5Ctimes7%7D)
![P=\dfrac{1}{2}](https://tex.z-dn.net/?f=P%3D%5Cdfrac%7B1%7D%7B2%7D)
Hence, The probability that the coin will land on an area that is white is
.

49%21=70
Answer:
m=56
Step-by-step explanation:
So look at the angles. I learned this in geometry like 2 years ago. I believe it was the opposite angle theorem or the alternate exterior or interior angles. You should look on the internet about that.
