The perimeter should be about 66
Answer:
![m = 10\sqrt 3](https://tex.z-dn.net/?f=m%20%3D%2010%5Csqrt%203)
![n = 10](https://tex.z-dn.net/?f=n%20%3D%2010)
Step-by-step explanation:
Required
Find m and n
Considering the given angle, we have:
![\sin(60) = \frac{Opposite}{Hypotenuse}](https://tex.z-dn.net/?f=%5Csin%2860%29%20%3D%20%5Cfrac%7BOpposite%7D%7BHypotenuse%7D)
This gives:
![\sin(60) = \frac{m}{20}](https://tex.z-dn.net/?f=%5Csin%2860%29%20%3D%20%5Cfrac%7Bm%7D%7B20%7D)
Make m ths subject
![m = 20 * \sin(60)](https://tex.z-dn.net/?f=m%20%3D%2020%20%2A%20%5Csin%2860%29)
![\sin(60) =\frac{\sqrt 3}{2}](https://tex.z-dn.net/?f=%5Csin%2860%29%20%3D%5Cfrac%7B%5Csqrt%203%7D%7B2%7D)
So, we have:
![m = 20 *\frac{\sqrt 3}{2}](https://tex.z-dn.net/?f=m%20%3D%2020%20%2A%5Cfrac%7B%5Csqrt%203%7D%7B2%7D)
![m = 10\sqrt 3](https://tex.z-dn.net/?f=m%20%3D%2010%5Csqrt%203)
Considering the given angle again, we have:
![\cos(60) = \frac{Adjacent}{Hypotenuse}](https://tex.z-dn.net/?f=%5Ccos%2860%29%20%3D%20%5Cfrac%7BAdjacent%7D%7BHypotenuse%7D)
This gives:
![\cos(60) = \frac{n}{20}](https://tex.z-dn.net/?f=%5Ccos%2860%29%20%3D%20%5Cfrac%7Bn%7D%7B20%7D)
Make n the subject
![n = 20 * \cos(60)](https://tex.z-dn.net/?f=n%20%3D%2020%20%2A%20%5Ccos%2860%29)
![\sin(60) =\frac{1}{2}](https://tex.z-dn.net/?f=%5Csin%2860%29%20%3D%5Cfrac%7B1%7D%7B2%7D)
So, we have:
![n = 20 *\frac{1}{2}](https://tex.z-dn.net/?f=n%20%3D%2020%20%2A%5Cfrac%7B1%7D%7B2%7D)
![n = 10](https://tex.z-dn.net/?f=n%20%3D%2010)
It was about 17.4%

Then divide that by actual value
Answer:
the third one
Step-by-step explanation:
y+8= 4(x-3)
y+8= 4x-12
y= 4x-20
C(x)-R(x)= P(x)
