We can use the vertical angle theorem which states that any two opposite angles are congruent. So, you can just set the two measures equal to each other and solve for x:
![7x-99=2x+1](https://tex.z-dn.net/?f=7x-99%3D2x%2B1)
![5x-99=1](https://tex.z-dn.net/?f=5x-99%3D1)
![5x=100](https://tex.z-dn.net/?f=5x%3D100)
![x = \frac{100}{5} = 20](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B100%7D%7B5%7D%20%3D%2020)
So, your answer is
20°.
You can search on goggle or watching YouTube videos
70-80=10
hope this help the
68 rounded to the nearest tenth equals 70
and 76 rounded to the nearest tenth equals 80
so if you subtract 80-70=10 Tito increased the percent up to 10 dollars
Both linear and proportional because as x increases y decreases at the same rate
