It’s A i did the test myself..
1) 70
2) 110
3) 70
because 110 is equivalent to angle 2. angle 1 and 3 are also equivalent so you add 110 + 110 which equals 220 and subtract 360-220 which equals 140 and divide by 2 to get angles 1 and 3.
the answer is C.
12a -18s =36
(12 adult tickets= 12a) - (18 student tickets =18s) =$36
