Step-by-step explanation:
The plane will make an angle
with the runway.
Explanation:
Given that the plane is flying at an altitude of 11 miles and is 193 miles from the runway, as measured from the ground.
We need to determine the angle that the plane will make with the runway.
From the given measurements, we can see that it is a right angled triangle. Hence, let us use the tangent formula to determine the angle.
The formula for the tangent is given by
![tan \ \theta=\frac{opp}{adj}](https://tex.z-dn.net/?f=tan%20%5C%20%5Ctheta%3D%5Cfrac%7Bopp%7D%7Badj%7D)
Where
and
Substituting these values in the above equation, we get,
![tan \ \theta=\frac{11}{193}](https://tex.z-dn.net/?f=tan%20%5C%20%5Ctheta%3D%5Cfrac%7B11%7D%7B193%7D)
Dividing, we get,
![tan \ \theta=0.057](https://tex.z-dn.net/?f=tan%20%5C%20%5Ctheta%3D0.057)
Taking
on both sides of the equation, we get,
![\theta= tan^{-1}(0.057)](https://tex.z-dn.net/?f=%5Ctheta%3D%20tan%5E%7B-1%7D%280.057%29)
Simplifying, we have,
![\theta= 3.26^{\circ}](https://tex.z-dn.net/?f=%5Ctheta%3D%203.26%5E%7B%5Ccirc%7D)
Hence, the angle that the plane will make with the runway is ![3.26^{\circ}](https://tex.z-dn.net/?f=3.26%5E%7B%5Ccirc%7D)
