Prakrit bought a pack of paper for $5.69 and printer toner for $9.76. he paid with a $20 bill. what was his change?

$4.55 my dude. You add them together and subtract the sum from 20

5.69 + 9.76 = 15.45

20 - 15.45 = 4.55

$4.55

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
