Oliver would like to buy a new ipod for $115. so far he have saved $40. if he earns $7.50 per hour. how many hours must he work until he can buy the ipod

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

Graph a should be your answer

How am i goonna know explain
