Use the diagram and cosine function to find the value of x.

D
--
x=9.4cos(58°)
because the cosine function uses the ratio of the adjacent side to that of the hypotenuse.
9.4 is the hypotenus the ration is 58 degrees I believe
[tex]\\ \rm\Rrightarrow cosA=\dfrac{Base}{Hypotenuse}[/tex]
[tex]\\ \rm\Rrightarrow cos58=\dfrac{x}{9.4}[/tex]
[tex]\\ \rm\Rrightarrow x=9.4cos58[/tex]
Option D
