Tiffany and Brianna each bought a pair of headphones and some new songs. Tiffany bought 12 songs and spent $44, while Brianna bought 20 songs and spent $50. How much did the headphones and each song cost?

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
