The angle sum of a triangle is 180 degrees
So add all the angles inside and equate it to 180: 5x+2x+3x= 180
10x=180
x= 18
Because you’re finding angle L, which is 3x, and we find what the numerical value of x is
Angle L = 3x18 = 54.
Hope this helps!
Answer:
9 scarves.
Step-by-step explanation:
We have been given that the number N of scarves Ariana can make is inversely proportional to the area A of each scarf.
We know that equation of two inversely proportional quantities in in form
, where, k is constant of variation and y is inversely proportional to x.
Let us find constant of variation using our given information.
![N=\frac{k}{A}](https://tex.z-dn.net/?f=N%3D%5Cfrac%7Bk%7D%7BA%7D)
![15=\frac{k}{3}](https://tex.z-dn.net/?f=15%3D%5Cfrac%7Bk%7D%7B3%7D)
![15*3=\frac{k}{3}*3](https://tex.z-dn.net/?f=15%2A3%3D%5Cfrac%7Bk%7D%7B3%7D%2A3)
![45=k](https://tex.z-dn.net/?f=45%3Dk)
Now, we will substitute
in our equation to solve for N.
![N=\frac{45}{5}](https://tex.z-dn.net/?f=N%3D%5Cfrac%7B45%7D%7B5%7D)
![N=9](https://tex.z-dn.net/?f=N%3D9)
Therefore, Ariana can make 9 scarves.

Answer:
She will still need about 450$
Step-by-step explanation:
So from what I have learned, she will need to work in order to get the money, but even when she is working, she may have expenses to pay and she may not make it, but she will because she can do loans and when she earns the money from loans, then she can pay, then she may have left over money she can use while on trip.
H(17) = 17
