Question

For the following right triangle, find the side length x. Round your answer to the nearest hundredth9X6

Answer 1

Step-by-step explanation:

To calculate the length of side x we ​​must use one of the trigonometric functions.

We have the hypotenuse and the value of the opposite leg; now we must calculate the adjacent leg.

The exercise is as follows:

`\begin{gathered} a=9 \\ b=6 \\ c=x \\ c=\sqrt[]{a^2-b^2} \\ c=\sqrt[]{(9)^2-(6)^2} \\ c=\sqrt[]{81-36} \\ c=\sqrt[]{45} \\ c=6.7 \\ \\ \text{the answer is x}=6.7 \end{gathered}`

To check if it is ok we must replace the values ​​and find the hypotenuse.
