Answer:
a) ![h=286.8ft](https://tex.z-dn.net/?f=h%3D286.8ft)
b) ![\frac{dh}{dt}=5.7ft/s](https://tex.z-dn.net/?f=%5Cfrac%7Bdh%7D%7Bdt%7D%3D5.7ft%2Fs)
Step-by-step explanation:
From the question we are told that:
Angle ![\theta=35](https://tex.z-dn.net/?f=%5Ctheta%3D35)
a)
Slant height ![h_s=500ft](https://tex.z-dn.net/?f=h_s%3D500ft)
Generally the trigonometric equation for Height is mathematically given by
![h=h_ssin\theta](https://tex.z-dn.net/?f=h%3Dh_ssin%5Ctheta)
![h=500sin35](https://tex.z-dn.net/?f=h%3D500sin35)
![h=286.8ft](https://tex.z-dn.net/?f=h%3D286.8ft)
b)
Rate of release
![\frac{dl}{dt}=10ft/sec](https://tex.z-dn.net/?f=%5Cfrac%7Bdl%7D%7Bdt%7D%3D10ft%2Fsec)
Generally the trigonometric equation for Height is mathematically given by
![h=lsin35](https://tex.z-dn.net/?f=h%3Dlsin35)
Differentiate
![\frac{dh}{dt}=\frac{dl}{dt}sin35](https://tex.z-dn.net/?f=%5Cfrac%7Bdh%7D%7Bdt%7D%3D%5Cfrac%7Bdl%7D%7Bdt%7Dsin35)
![\frac{dh}{dt}=10sin35](https://tex.z-dn.net/?f=%5Cfrac%7Bdh%7D%7Bdt%7D%3D10sin35)
![\frac{dh}{dt}=5.7ft/s](https://tex.z-dn.net/?f=%5Cfrac%7Bdh%7D%7Bdt%7D%3D5.7ft%2Fs)
