Let's start by identify a 30-60-90 triangle
If we compare those two traingles we can stablish the following relation:
Therefore, a=6
u is the opposite side to the 90° angle, therefore
on the other hand, v is the opposite side to the 30° angles, so
Inverse variation means
When the value of x increases the value of y decreases.
When the value of x decreases the value of y increases.
So for an inverse variation we have the expression
or
The expression which represents this condition is
Hence option b) or the second option is the right answer.
