Answer:

D.) 10.4 yd

Step-by-step explanation:

In the given figure the alternate angles are equal and hence a right angle triangle with one of its angle as 30 degree is formed .

For angle 30 degrees adjacent side is 18 yard and opposite side is x.

Tan of an angle is equal to [tex]\frac{opposite}{adjacent}[/tex]

[tex]Tan 30=\frac{x}{18}[/tex]

x=Tan 30 (18)

x= 10.39

x= 10.4 yard (rounded  to tenth place)

Option D is the right answer.
