An Isosceles triangle has two even parts, you add them up. For example 60 degree plus another 60 degree angle is 120 degrees. And the limit is 180 degrees, so in order to get that last angle, you'd have to subtract 160 from 180. And that'd be 20 degrees. I couldn't see the question but I hope this helps you in a way
If it was my store I would have a camera in every corner of the store to get every angle. So to get the official answer I suggest you to count how many corners there are throughout the store and that will be your answer.
Hope this helps!
