Third angle is ![130-7x](https://tex.z-dn.net/?f=130-7x)
Step-by-step explanation:
We have sum of angles is ![180^{0}](https://tex.z-dn.net/?f=180%5E%7B0%7D)
Let the third angle be ![y](https://tex.z-dn.net/?f=y)
Hence
![5x+20+2x+30+y=180\\\\y=130-7x](https://tex.z-dn.net/?f=5x%2B20%2B2x%2B30%2By%3D180%5C%5C%5C%5Cy%3D130-7x)
Third angle is ![130-7x](https://tex.z-dn.net/?f=130-7x)
