Answer 1

Answer:

Option A $\sqrt{187.95}\ Km$

Step-by-step explanation:

we know that

Applying the Pythagorean Theorem

$c^2=a^2+b^2$

where

c is the greater side (the hypotenuse)

a and b are the legs

we have

$a=3.7\ Km$ ----> the height of the airplane

$c=14.2\ Km$ ---> slant distance from the airport

substitute

$14.2^2=3.7^2+b^2$

solve for b

$b^2=14.2^2-3.7^2$

$b^2=187.95$

$b=\sqrt{187.95}\ Km$
