Hi there!

Assuming all are equal slices, we know that each slice would contain 30 degrees. Knowing this, 7 of the slices were served, so 5 are left. By multiplying 5 x 30, we can figure out the angle measure of the remaining portion of the cake. Doing this leaves us with 150 degrees left.

Hope this helps!! :)
