Answer:
The expression of h as function of x is h =

Explanation:
Given as :
The distance of blimp (AB) = 5500 feet
The slanted distance to the pagoda (BC) = d feet
The horizontal distance (AC) = h
Let the angle made between slanted distance and horizontal distance be Ф
So , cos Ф =
=

And sin Ф =
=

∵, cos²Ф = 1 - sin²Ф
So,
=

Or,
=
Or, h² = d² - 5500²
∴ h =

Or, h =

Hence The expression of h as function of x is h =
