Casey took 25 tests in 135 days at this rain and how many days will she take another 10 tests

189 because if you divide 135/25 you will get 5.4. (to find how many tests she takes a day).
If you multiply 5.4 times 35 (you add the 10) you get 189.

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
