Answer:
43°
Step-by-step explanation:
The first thing you should do is make the equation. We should know that the sum of all the angles is 180. So it should look like this...
![49+88+x=180](https://tex.z-dn.net/?f=49%2B88%2Bx%3D180)
Combine like terms:
![137+x=180](https://tex.z-dn.net/?f=137%2Bx%3D180)
Subtract the 137 on both sides:
![x= 43](https://tex.z-dn.net/?f=x%3D%2043)
That's it the value of v is 43°.
Answer:
This year the parking lot should have 16 spaces for RVs
Step-by-step explanation:
we know that
using proportion
![\frac{66}{104-r}=\frac{12}{r}](https://tex.z-dn.net/?f=%5Cfrac%7B66%7D%7B104-r%7D%3D%5Cfrac%7B12%7D%7Br%7D)
solve for r
Multiply in cross
![(66)(r)=(104-r)(12)](https://tex.z-dn.net/?f=%2866%29%28r%29%3D%28104-r%29%2812%29)
![66r=1,248-12r](https://tex.z-dn.net/?f=66r%3D1%2C248-12r)
![78r=1,248](https://tex.z-dn.net/?f=78r%3D1%2C248)
![r=16](https://tex.z-dn.net/?f=r%3D16)
therefore
This year the parking lot should have 16 spaces for RVs
x ----> the number of car spaces
r ----> the number of RV spaces
we know that
![\frac{x}{r}=\frac{66}{12}=5.5](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7Br%7D%3D%5Cfrac%7B66%7D%7B12%7D%3D5.5)
----> equation A
----> equation B
substitute equation A in equation B
solve for r

460= 40+ 12x
X equal the cost per month, which is what we're looking for.
460=40 +12x
-40 -40
420=12x
420/12= 35
So they would pay $35 per month with the $40 fee, as seen in the $460 fee.
