B
Step-by-step explanation:
First of all, quick reminder SINE is Opposite/Hypotenuse. Using 30-60-90 we can find out that BC is 6, and AC is 12.
A is false because BC/AC= 1/2 not sqrt(3)/2
B is true because AB/AC= sqrt(3)/2
C is false due to 30-60-90 (AB is 6Sqrt(3) and BC cant be that)
D is false due to 30-60-90 (AB is 6Sqrt(3) and BC cant be that)

Answer:
equation 2into minus 3 into equation 1
8x+ 3y= -28
-3x-3y=18
----------------
5x=10
x =2
put value of y in equation 2
8 into 2+3y=-28
16+3y= -28
3y= -28+16
3y= -12
y= -4
