Hi,
We can simply use the formula: 180(n-2)=180(7-2)=900
I could have used the exterior angle property but for that we need to be sure that this is a regular figure I.e. all the angles and sides are of equal length. But here we are not given that the above figure is a regular figure so we can use the formula instead.
Hope this helps!
