Question

Find the value of x. Round to the
nearest tenth.
12
x=[?]

Answer 1

17.1

Explanation:

Given we have one side and one degree, we can use the trigonometric function "tangent" to solve this right triangle.

Remember that tangent is opposite side over adjacent side, so lets set up the equation:

`tan(35)=(12)/(x)`

Now solve:

`x(tan(35))=12\\x=(12)/(tan(35))`

As a result, x is equal to approximately 17.1
