Question

Find the value of x. Use trigonometry and draw the diagram.

Answer 1

The answer is 5.73 that’s the answer

Answer 2

Given is a right triangle.

We know that the ratio of cosine is defined as "adjacent" over "hypotenuse".

With respect to the angle given, we see that

• x is the adjacent side

,

• 7 is the hypotenuse

Thus, we can write:

`\cos 35=(x)/(7)`

Now, we can cross-mutliply and figure out the length of "x". Shown below:

`\begin{gathered} \cos 35=(x)/(7) \\ x=7*\cos 35 \\ x=5.73 \end{gathered}`Answerx = 5.73
