Answer:

x = 13

Explanation:

Right Triangles

In a right triangle, there is an internal angle of 90°. The other two must add up to 90°.

The trigonometric ratios are satisfied in a right triangle. The tangent ratio, for example, is defined as:


\displaystyle \tan 35^\circ=\frac{\text{opposite leg}}{\text{adjacent leg}}

The angle of 35° is adjacent to the side of length 18 and is opposite to the side of length x, thus:


\displaystyle \tan 35^\circ=(x)/(18)

Solving for x:


x=18\tan 35^\circ

This is the equation to solve. Now substitute the tangent for its value to get

x = 13
