Answer: The value of cos (x) of the dilated triangle would be exactly the same as in the first triangle, cos (8/17).

The cosine ratio is a ratio of two sides.

In the first triangle the ratio is 8/17.

In the second triangle the ratio is 16/34. This could be reduced back to 8/17 which would produce the same cosine value.
