Answer:
90 degrees
Step-by-step explanation:
This is an... odd question. There isn't any picture provided, but I'll see what I can do.
I pizza is generally a 360* circle, and is cut into 8 pieces.
At that, we'll do 360* / 8 to get the length of each slice.
That comes out to 45*.
If you're two slices away from the piece you want, you have to turn it 45* twice, or 45 x 2, which is 90.
You'll want to turn the pizza 90*.
Hope this helps?
