The opposite and adjacent are given in the right-angled triangle and this means that the value of the tangent for the angle can be determined as the quotient between the opposite and the adjacent:

\displaystyle \tan v = 2/5 Image:4_2_2_a.gif

At the same time, this is a trigonometric equation for the angle v.


Note: In the chapter on "Trigonometric equations", we will investigate more closely how to solve equations of this type.
