The sixth graders at Amir’s school voted for the location of their class trip. 35% of the students voted to go to the art museum. If 126 students voted for going to the art museum, how many sixth graders are at Amir’s school?

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
