Answer:
tan (40°) = [tex]\frac{x}{100}[/tex]
Step-by-step explanation:
tan [tex]\theta[/tex] = [tex]\frac{opposite}{adjacent}[/tex]
The opposite side to angle B is x. The adjacent side to angle B is 100 ft.
tan 40° = x/100
As, AC is perpendicular and BC is the with respect to angle ABC. So, tan 40° will be use to determine the distance in feet from point C to point A.
tan ABC = perpendicular/base
tan 40° = AC/BC
tan 40° = x/100 feet
