The third trig function, tangent, is abbreviated tan. This function uses just the measures of the two legs and doesnt use the hypotenuse at all. Tabor College, Bachelor of Science, Mathematics Teacher Education. Step 3 Calculate Opposite/Adjacent = 300/. {/eq} Using the fact that {eq}\angle \hat{C} = 30^{\circ} {/eq} gives {eq}\tan 30^{\circ} = \displaystyle \frac{BA}{CA} \implies \displaystyle \frac{\sqrt{3}}{3} = \displaystyle \frac{3}{CA} \implies CA = 3\sqrt{3} {/eq}. An alternative definition to the definition of a tangent is the ratio between the sine and the cosine of an angle, where the sine is, by definition, the ratio between the opposite angle and the hypothenuse, and the cosine, the ratio between the adjacent side and the hypothenuse. $$\begin{align*} \tan(\theta)&=\frac{\text{Opposite}}{\text{Adjacent}}\\ \tan(55^{\circ})&=\frac{12}{\text{Horizontal}}\\ \text{Horizontal}&=\frac{12}{1.4}\\ \text{Horizontal}&=8.6\ \mathrm{units} \end{align*} $$, Become a member to unlock the rest of this instructional resource and thousands like it.
