What the prime factorization for 300

300 = 2 x 2 x 3 x 5 x 5

300 = 2² x 3 x 5²


2² x 3 x 5²

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
