3
B.

6
C.

6
⁢
3
D.

Answer 1

Answer: D

Explanation:

In these triangles there is a rule:

* the side across the 30 degree angle is "a"

* the side across the 60 degree angle is "a√¯3"

* the side across the 90 degree angle is "2a"

If we imply this rule, we find that 2a is equal to 6

so a = 3

and we are looking for the side across the 60 degree angle, which is a√¯3,

so the answer is 3√¯3

Answer 2

`6√(3)`

6=2x

3=x

`x√(3)`

`6√(3)`
