tan 29 = 12/x

To solve for x, we need to isolate it on one side of the equation.

We know that tan 29° = 12/x. Since tan is equal to the ratio of the opposite side to the adjacent side, we can rewrite this equation as:

12/x = tan 29°

Now, let's multiply both sides of the equation by x to eliminate the fraction:

12 = x * tan 29°

Lastly, divide both sides of the equation by tan 29° to solve for x:

x = 12 / tan 29°

Using a calculator, we find that tan 29° is approximately 0.5543.

Therefore, x = 12 / 0.5543 ≈ 21.656.

Hence, x is approximately 21.656.
