Answer:
C. 73 if I have read the given angle measurements correctly.
The angle measurements I see are:
![219^\circ](https://tex.z-dn.net/?f=219%5E%5Ccirc)
![(x-50)^\circ](https://tex.z-dn.net/?f=%28x-50%29%5E%5Ccirc)
.
Step-by-step explanation:
Those angles together form a full rotation. A full rotation is equal to 360 degrees.
So we have the following equation to solve:
![219+(x-50)+(x+45)=360](https://tex.z-dn.net/?f=219%2B%28x-50%29%2B%28x%2B45%29%3D360)
Combine like terms:
![(x+x)+(219-50+45)=360](https://tex.z-dn.net/?f=%28x%2Bx%29%2B%28219-50%2B45%29%3D360)
Simplify:
![2x+(219-5)=360](https://tex.z-dn.net/?f=2x%2B%28219-5%29%3D360)
![2x+214=360](https://tex.z-dn.net/?f=2x%2B214%3D360)
Divide both sides be 2:
![x+107=180](https://tex.z-dn.net/?f=x%2B107%3D180)
Subtract 107 on both sides:
![x=180-107](https://tex.z-dn.net/?f=x%3D180-107)
![x=73](https://tex.z-dn.net/?f=x%3D73)
Answer: 50$
Step-by-step explanation:7.50 is 15% of what
7.50=.15x
50=x
answer is $50
● To do this, you need to multiply 6.75 by 21 to find out how many meters are in all. 6.75×21 is 141.75
● Next you multiply 141.75 by 2 to see how much it costs which is 283.5
● Since we're dealing with money, it would have two place values so we add a zero and we get $283.50
