The answer is B.27. Hope this helps!
I think its 12... Because theres 6 side on the dice and 2 on the coin so you have 6 outcomes for each side of the coin
4x+9+8x+3=180
12x+12=180
12x=180-12
12x=168
x=168/12
x=14
1. Q= 4x+9
4(14) +9
56+9
Q= 65
2. R= 8x+3
8(14) +3
112+3
R= 115
here we are given that sum of angle and its supplement is 180
let us say one of the angle is x.
So the other angle is 2x
adding the two angles,
x+2x=180
3x=180
x=60
2x=2*60=120
so the two angles are 60 and 120
