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.
Answer:
4√6^3
Step-by-step explanation:
Answer:
if you put 4.25 on a number line then the OPPOSITE of that would be going across the 0 on the number line so the answer -4.25
Step-by-step explanation:
if the number is negative its opposite is that number but positive and the same thing if the number is positive its opposite is a negative
Answer:
<, -4
Step-by-step explanation:
-8x-20<12
add 20 to both sides
-8x=32
divide both sides by -8
x=-4
(x2 +1) (x2-4) (mark as brainiest)
