165° = (15 + 10x)°
- 15° - 15°
_____________
![\displaystyle \frac{150°}{10} = \frac{[10x]°}{10} \\ \\](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7B150%C2%B0%7D%7B10%7D%20%3D%20%5Cfrac%7B%5B10x%5D%C2%B0%7D%7B10%7D%20%5C%5C%20%5C%5C)
[Plug this back into the modeled expression for the
to get the angle measure of 30°];
