Answer:
x = 23.78
Step-by-step explanation:
From the information given, we can construct the triangle shown in the attached picture.
With respect to the angle 18, we have the hypotenuse (25) and we want to know the adjacent side (x). Thus, what trigonometric ratio relates adjacent to hypotenuse? COSINE! Thus we can set-up the ratio shown below and compute x.
[tex]Cos (18)=\frac{x}{25}\\x=25*Cos(18)\\=23.78[/tex]
