1/2.165 = sqrt x/131.29.

I am not sure how to solve for x.

To solve for x in the equation:

1/2.165 = sqrt(x/131.29)

We can follow these steps:

Step 1: Begin by squaring both sides of the equation to eliminate the square root.
(1/2.165)^2 = (sqrt(x/131.29))^2

Step 2: Simplify both sides of the equation.
1/4.688225 = x/131.29

Step 3: Cross-multiply by multiplying both sides of the equation by 131.29.
(1/4.688225) * 131.29 = x

Step 4: Evaluate the left side of the equation.
x = 28.093

Therefore, x is approximately 28.093.
