Answer:
2/1
Step-by-step explanation:
8/4 which is also 2/1
MAB is 120, so m∠ADB is half of mAB=60
AC is the diameter, which means arc ABC is 180, and m∠ADC=90
m∠BDC=m∠ADC-m∠ADB=90-60=30
so the angle BDC is 30 degree
{x+1=y}
{2x-y=0}
X+1=y
X=y-1
{2(y-1)-y=0}
{2y-2-y=0
{y-2=0}
{y=2}
Since y=2, and there’s only one ordered pair with y=2, the answer is B
