Answer:
b = 9
Step-by-step explanation:
A= 30° a = 3[tex]\sqrt{3x}[/tex]
B = b =
C = 90° c =
find B first
90 + 30 = 120
180 - 120 = 60
B = 60°
Now, let's find b
use the Law of Sines
[tex]\frac{sin A}{a} = \frac{sin B}{b} \\\frac{sin 30}{3\sqrt{3} } = \frac{sin 60}{b}\\b = \frac{3\sqrt{3} sin 60 }{sin 30}\\b = 9[/tex]
