Question

Hello can you assist me please i need to solo e and Identity sine cosine or tangent and identify opposite hypnose or adjeact.Number 11.

Answer 1

Given the Right Triangle shown in the exercise, you need to use the following Trigonometric Function in order to find the measure of "x":

$tan\alpha=\frac{opposite}{adjacent}$

In this case, you can identify that:

$\begin{gathered} \alpha=21° \\ opposite=x \\ adjacent=18 \end{gathered}$

Then, by substituting values and solving for "x", you get:

$\begin{gathered} tan(21\text{\degree})=\frac{x}{18} \\ \\ 18\cdot tan(21\text{\degree})=x \end{gathered}$$x\approx6.9$

Hence, the answer is:

$x\approx6.9$
