Answer:
163.75
Step-by-step explanation:
a scale factor applies normally to lengths (one-dimensional sizes).
and the perimeter is calculated just by lengths (the side lengths).
so, we can apply the scaling factor directly to the perimeter.
perimeter of DEF = 5/2 × perimeter of ABC = 5/2 × 65.5 =
= 163.75 ft
what was step 1 ? we did not need it ?

Answer:
c=6p
Step-by-step explanation:
you multiply
6 dollars per pound by p pounds
pounds cancel out and you are left with dollars
that is the cost
Answer:
![X=85.123m](https://tex.z-dn.net/?f=X%3D85.123m)
![Y=184.88m](https://tex.z-dn.net/?f=Y%3D184.88m)
Step-by-step explanation:
From the question we are told that:
Campfire Bearing from Colonel![x=N 71 \textdegree E](https://tex.z-dn.net/?f=x%3DN%2071%20%5Ctextdegree%20E)
Distance b/w Colonel and Sarge ![Z=235feet](https://tex.z-dn.net/?f=Z%3D235feet)
Campfire Bearing from Sarge
Generally the angles x' and y' are solved
![x'=90 \textdegree-71 \textdegree](https://tex.z-dn.net/?f=x%27%3D90%20%5Ctextdegree-71%20%5Ctextdegree)
![x'=19 \textdegree](https://tex.z-dn.net/?f=x%27%3D19%20%5Ctextdegree)
![y'=90 \textdegree-45 \textdegree](https://tex.z-dn.net/?f=y%27%3D90%20%5Ctextdegree-45%20%5Ctextdegree)
![y'=45 \textdegree](https://tex.z-dn.net/?f=y%27%3D45%20%5Ctextdegree)
Generally the angle z' is solved
Sum of angles of a triangle is 180
Therefore
![z'=180 \textdegree-(19+45) \textdegree](https://tex.z-dn.net/?f=z%27%3D180%20%5Ctextdegree-%2819%2B45%29%20%5Ctextdegree)
![z'=116 \textdegree](https://tex.z-dn.net/?f=z%27%3D116%20%5Ctextdegree)
Generally the sine rule equation for for all distances is mathematically given by
![\frac{Z}{sinz'}=\frac{X}{sinx'}=\frac{Y}{siny}](https://tex.z-dn.net/?f=%5Cfrac%7BZ%7D%7Bsinz%27%7D%3D%5Cfrac%7BX%7D%7Bsinx%27%7D%3D%5Cfrac%7BY%7D%7Bsiny%7D)
Generally the the distance b/w the Colonel and the campfire X is mathematically given as
![\frac{235}{sin116}=\frac{X}{sinx'}](https://tex.z-dn.net/?f=%5Cfrac%7B235%7D%7Bsin116%7D%3D%5Cfrac%7BX%7D%7Bsinx%27%7D)
![\frac{235}{sin116}=\frac{X}{sin19}](https://tex.z-dn.net/?f=%5Cfrac%7B235%7D%7Bsin116%7D%3D%5Cfrac%7BX%7D%7Bsin19%7D)
![X=85.123m](https://tex.z-dn.net/?f=X%3D85.123m)
Generally the the distance b/w Sarge and the campfire X is mathematically given as
![\frac{235}{sin116}=\frac{Y}{siny}](https://tex.z-dn.net/?f=%5Cfrac%7B235%7D%7Bsin116%7D%3D%5Cfrac%7BY%7D%7Bsiny%7D)
![\frac{235}{sin116}=\frac{Y}{sin45}](https://tex.z-dn.net/?f=%5Cfrac%7B235%7D%7Bsin116%7D%3D%5Cfrac%7BY%7D%7Bsin45%7D)
![Y=184.88m](https://tex.z-dn.net/?f=Y%3D184.88m)
Answer:
Scalene Triangle
Step-by-step explanation:
Measure the side and if the none of the sides are equal then it will be a scalene triangle
