Question

-9
- 12 square root of 3
​

Answer 1

b = 9

Explanation:

A= 30° a = 3
`√(3x)`

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

`(sin A)/(a) = (sin B)/(b) \\(sin 30)/(3√(3) ) = (sin 60)/(b)\\b = (3√(3) sin 60 )/(sin 30)\\b = 9`
