Answer:
x=95.22
Step-by-step explanation:
We could use trigonometric ratios to do this.
Cosine is a trigonometric function in which it is equal to the ration of the adjacent side to the hypotenuse.
We need to find the angle, so it goes like this:
[tex]cosine(35)=x/78\\[/tex]
x is approximately 95.22
