40% of 20 equals 8.

First, we need to think that 20 is our 100%.
Let's make the variable v as the value we're looking for.

20/v = 100/40
We need to multiply both sides of the equation by v.
(20/v) * v = (100/40) * v

Now, we're left with 20 = 2.5x

We need to divide both sides of the equation to isolate the variable x.
20/2.5 = 2.5x/2.5
8 = x

Our final answer is 8.

Answer:

x = 150

D

Step-by-step explanation:

1 / tan(90 - x) = -√3/3                   Cross multiply

3 = -√3 * tan(90 - x)                     Divide by -√3

3/-√3 = tan(90 - x)                       Rationalize the denominator

3 * √3 /  (- √3 * √3  ) =tan(90-x)

3 * √3 / - 3 = tan(90 - x)               Divide

- √3           = tan(90 - x)               Take the inverse tan of -√3

tan-1(-√3) = 90 - x

-60 = 90 - x                                  Add x to both sides.

x - 60 = 90                                   Add 60 to both sides

x = 150
