Answer:
x = 12
Step-by-step explanation:
![90 + 3x + 16 + 2x + 14 = 180](https://tex.z-dn.net/?f=90%20%2B%203x%20%2B%2016%20%2B%202x%20%2B%2014%20%3D%20180%20)
![5x + 120 = 180](https://tex.z-dn.net/?f=5x%20%2B%20120%20%3D%20180)
![5x = 180 - 120](https://tex.z-dn.net/?f=5x%20%3D%20180%20-%20120)
![5x = 60](https://tex.z-dn.net/?f=5x%20%3D%2060)
![x = \frac{60}{5} = 12](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B60%7D%7B5%7D%20%20%3D%2012)
