Antwon made some hot chocolate by mixing $$2 cups of milk with $$5 tablespoons of cocoa. How many cups of milk would he need for 1 tablespoon of cocoa?

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
