Answer:
17.78 meters
Step-by-step explanation:
Let
x ----> the horizontal distance, in meters, to home plate
[tex]\theta[/tex] ----> the angle of vision
we know that
[tex]tan(\theta)=\frac{40}{x}[/tex] ----> by TOA (opposite side divided by the adjacent side)
we have
[tex]tan(\theta)=\frac{9}{4}[/tex]
substitute
[tex]\frac{9}{4}=\frac{40}{x}[/tex]
solve for x
[tex]x=40(4)/9\\x=17.78\ m[/tex]
