Answer:
![X=49ft](https://tex.z-dn.net/?f=X%3D49ft)
Step-by-step explanation:
From the question we are told that:
Height of Eagle ![h=40ft](https://tex.z-dn.net/?f=h%3D40ft)
Angle of depression
Generally the trigonometry equation for diagonal X is mathematically given by
![Cos\theta \textdegree=\frac{Adjacent}{Hypotenuse} }](https://tex.z-dn.net/?f=Cos%5Ctheta%20%5Ctextdegree%3D%5Cfrac%7BAdjacent%7D%7BHypotenuse%7D%20%7D)
![Cos\theta \textdegree=\frac{h}{X} }](https://tex.z-dn.net/?f=Cos%5Ctheta%20%5Ctextdegree%3D%5Cfrac%7Bh%7D%7BX%7D%20%7D)
![X=\frac{40}{Cos 35 } }](https://tex.z-dn.net/?f=X%3D%5Cfrac%7B40%7D%7BCos%2035%20%7D%20%7D)
![X=48.83ft](https://tex.z-dn.net/?f=X%3D48.83ft)
![X=49ft](https://tex.z-dn.net/?f=X%3D49ft)

Mode :))))))))))))))))))))
Step-by-step explanation:
The final price is the cost plus the tax.
Since we know the tax and a percent, we can write this as
T = C(1+r)
T = what Graham paid = $87.45
C = cost before tax
r = tax rate expressed as a decimal = .40
Plugging in what we know
87.45 = C (1+.4)
87.45 = C(1.4)
Divide both sides by 1.4
C = $62.46
