Answer:
The line of sight distance is 1285.58 feet.
Step-by-step explanation:
The situation is illustrated in the figure attached.
From the figure we see that the altitude difference of the planes and the distance between them form a right triangle with one angle of 40° .
The line of sight between the two planes is the hypotenuse of the triangle.
The altitude difference of the planes is
Therefore, if we call the line of sight distance, from trigonometry we have
Therefore, the line of sight distance (x) is 1285.58 feet.
You always have to switch the inequality symbol when dividing by a negative because a negative always negates a number's (other than 0) original sign.
