One cup of whole milk has 8 grams of fat. how many grams of fat are in a gallon of whole milk? explain to me

There are 16 cups in a gallon; multiply 16 by 8 and you’d get 128 grams of fat in a gallon of whole milk.

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
