Answer 1

`x=67.38^\circ`

Explanation:

Use trigonometry

Recall that cos(x)=adjacent side/hypotenuse

You can remember this with SohCahToa

Also remember that if cos(x)=y then
`cos^(-1)(y)=x`

In this case, we know the adjacent side and hypotonous

Adjacent side=5000

Hypotenuse=13000

Therefore

`Cos(x)=(5000)/(13000)=(5)/(13)`

Now to solve for x, take the inverse cosine

`cos^(-1)((5)/(13))=x=67.38^\circ`
