Answer:
125
Step-by-step explanation:
Sum of Exterior Angles must add to 360 so
![60 + 70 + 40 + 65 + x = 360](https://tex.z-dn.net/?f=60%20%2B%2070%20%2B%2040%20%2B%2065%20%2B%20x%20%3D%20360)
![235 + x = 360](https://tex.z-dn.net/?f=235%20%2B%20x%20%3D%20360)
![x = 125](https://tex.z-dn.net/?f=x%20%3D%20125)
