Answer:
 km
 km
Step-by-step explanation:
The submarine's path from its base forms a right triangle when its final position is "connected" to the base. We know that the right triangle has legs of  km and
 km and  km, and we need to find the length of its hypotenuse. To do so, we can use the Pythagorean Theorem, which states that in a right triangle,
 km, and we need to find the length of its hypotenuse. To do so, we can use the Pythagorean Theorem, which states that in a right triangle,  , where
, where  and
 and  are the lengths of the triangle's legs and
 are the lengths of the triangle's legs and  is the length of the triangle's hypotenuse. In this case, we know what
 is the length of the triangle's hypotenuse. In this case, we know what  and
 and  are, and we need to solve for c, so after substituting the given values of
 are, and we need to solve for c, so after substituting the given values of  and
 and  into
 into  to solve for c, we get:
 to solve for c, we get:

Answer:
Brainliest?
Step-by-step explanation:
1.
subtract 1 from both sides
divide by 2
2.
add 5 to each side
divide by 4
