Step-by-step explanation:
A

10= 30 degrees 30+90= 120
11= 60 degrees 180-120= 60
12= 60 degrees 180-120 = 60
13= 120 degrees 180-60= 120
The answer to this question is c I think
1/2 (One and a half) since 12 and 12 are even and there would be a fifty fifty chance of getting one or the other or two of the same.
