A=3 square root of 3
B=3
C=7
D=6

Answer:
[tex]3\sqrt{3}[/tex]
Step-by-step explanation:
This triangle is a 30°-60°-90° triangle, so you should always remember the rule shown in the picture. Because y is across from the 60° angle, it will be [tex]x\sqrt{3}[/tex]. 3 is x because it is across from the 30° angle, so y will be [tex]3\sqrt{3}[/tex].
