Answer:
The expression of h as function of x is h =
Step-by-step 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 = Answer
