For this case we have an equation with a variable of the form . Where
. Given the value of
, we want to find the value of the variable "x". So, we have:
We must clear "x", for this, we add "19" to both sides of the equation:
We divide between "3" on both sides of the equation:
Thus, the value of the variable "x" is 30.
Answer:
Option A
Answer:
The horizontal distance from the plane to the tower is 2784.5 feet.
Step-by-step explanation:
From the given question, the height of the control tower is not given. But;
Tan θ =
Tan =
x = 13100 × Tan
= 2784.4910
Thus, x = 2784.5 feet
Therefore, the horizontal distance from the plane to the tower is 2784.5 feet.
