Lisa gets $ 50 for free. She buys colored pencils for $ 5.90, a book for $ 8, a CD for $ 12 50ct and 3 scoops of ice cream at 90ct each. She takes the rest to the bank. Before that, calculate how much Lisa's new savings account balance​

20.9 cause you just subtract everything from the original number

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
