Answer 1

Answer:

$x=67.38^\circ$

Step-by-step 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

$Cos(x)=\frac{5000}{13000}=\frac{5}{13}$

Now to solve for x, take the inverse cosine

$cos^{-1}(\frac{5}{13})=x=67.38^\circ$
