Option A
Option B
Option C
Option D​

Option d, because 6 can be divided by 2 and that’s 3, and 10 can be divided by 2 and that’s 5 !!

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
