Answer:
The perimeter of the triangle is ![12\ units](https://tex.z-dn.net/?f=12%5C%20units)
Step-by-step explanation:
Let
![A(-3,1),B(1,1),C(1,-2)](https://tex.z-dn.net/?f=A%28-3%2C1%29%2CB%281%2C1%29%2CC%281%2C-2%29)
we know that
The perimeter of triangle is equal to
![P=AB+BC+AC](https://tex.z-dn.net/?f=P%3DAB%2BBC%2BAC)
the formula to calculate the distance between two points is equal to
step 1
Find the distance AB
![A(-3,1),B(1,1)](https://tex.z-dn.net/?f=A%28-3%2C1%29%2CB%281%2C1%29)
substitute in the formula
step 2
Find the distance BC
![B(1,1),C(1,-2)](https://tex.z-dn.net/?f=B%281%2C1%29%2CC%281%2C-2%29)
substitute in the formula
step 3
Find the distance AC
![A(-3,1),C(1,-2)](https://tex.z-dn.net/?f=A%28-3%2C1%29%2CC%281%2C-2%29)
substitute in the formula
step 4
Find the perimeter
![P=AB+BC+AC](https://tex.z-dn.net/?f=P%3DAB%2BBC%2BAC)
substitute the values
![P=4+3+5=12\ units](https://tex.z-dn.net/?f=P%3D4%2B3%2B5%3D12%5C%20units)
Answer:
You must divide
by ![4](https://tex.z-dn.net/?f=4)
Step-by-step explanation:
we have
![\frac{2}{3}=\frac{x}{6}=\frac{9}{y}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D%3D%5Cfrac%7Bx%7D%7B6%7D%3D%5Cfrac%7B9%7D%7By%7D)
Step 1
Solve for x
![\frac{2}{3}=\frac{x}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D%3D%5Cfrac%7Bx%7D%7B6%7D)
![3x=6*2\\x=12/3\\x=4](https://tex.z-dn.net/?f=3x%3D6%2A2%5C%5Cx%3D12%2F3%5C%5Cx%3D4)
Step 2
Find the value of y
![\frac{x}{6}=\frac{9}{y}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B6%7D%3D%5Cfrac%7B9%7D%7By%7D)
Substitute the value of x
![\frac{4}{6}=\frac{9}{y}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B6%7D%3D%5Cfrac%7B9%7D%7By%7D)
![4y=9*6\\y=54/4\\y= 13.5](https://tex.z-dn.net/?f=4y%3D9%2A6%5C%5Cy%3D54%2F4%5C%5Cy%3D%2013.5)
therefore
You must divide
by ![4](https://tex.z-dn.net/?f=4)
Answer:
2.6 ft
Step-by-step explanation:
8.3/sin 90 = MK/sin 18
MK = 8.3 sin 18 / sin 90
MK = 2.6 ft
