Agroup of fitness club members lose a combined total of 28 kilograms in 1 week. there are approximately 2.2 pounds in 1 kilogram. assuming the weight loss happened at a constant rate, about how many pounds did the group lose each day?

The group lost 28/7 = 4 kilograms of weight each day.

1 kilogram = 2.2 pounds
4 kilograms = 2.2 x 4 = 8.8 pounds

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
