Greta uses 8 cups of pasta for every 8/9 cups of sauce how much pasta does she use per cup of sauce?

8 cups pasta for 8/9 cups sauce
1 cup pasta for 1/9 cup sauce
9 cups pasta for 1 cup sauce

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct
