Question 20

We have the given triangle

To get x, we will use the trigonometric relation

$\cos \theta=\frac{\text{adjacent}}{\text{hypotenuse}}$

Thus, we will have

$\cos 71^0=(x)/(20)$

To get x, we will cross multiply

$\begin{gathered} x=20\cos 71^0 \\ x=6.511 \end{gathered}$

The value of x is 6.51
