Answer:

A.
\text{tan}(20^(\circ))=(x)/(10)

Explanation:

We have been given a right triangle. We are asked to find the equation that can be used to solve for x.

We can see that x is opposite side of the 20 degree angle and side length of 10 units is adjacent side.

We know that tangent relates opposite side of right triangle to adjacent side.


\text{tan}=\frac{\text{Opposite}}{\text{Adjacent}}


\text{tan}(20^(\circ))=(x)/(10)

Therefore, our required equation is
\text{tan}(20^(\circ))=(x)/(10) and option A is the correct choice.
