Answer:
m∠2 = 90°
Step-by-step explanation:
Here's a postulate:
If a line is perpendicular to another line, then they make up 90° on both sides.
OR
If a⊥b, then ∠ are 90°

Answer:
![\frac{x + 2}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%20%2B%202%7D%7B3%7D%20)
Step-by-step explanation:
Replace y with f(x).
![y = 3x - 2](https://tex.z-dn.net/?f=y%20%3D%203x%20-%202)
Swap x and y and solve for y
![x = 3y - 2](https://tex.z-dn.net/?f=x%20%3D%203y%20-%202)
![x + 2 = 3y](https://tex.z-dn.net/?f=x%20%2B%202%20%3D%203y)
![\frac{x + 2}{3} = y](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%20%2B%202%7D%7B3%7D%20%20%3D%20y)
Inside I think because the intersection isn’t outside of the circle
