45 feet.
Absolute value is the distance of a number from 0. Say 0 is the surface of the ocean, then the diver is 45 feet away from it. Either from above or below, they are the same distance away.

Answer:

Step-by-step explanation:
For that transformation you just have to use polar coordinates, notice that when you use polar coordinates the radius is constant when the angles varies and the angle is constant when the radius varies. Therefore your transformation would be just
.
Let the distance between the two corners be AB.
Now, according to the pythagoras theorum,
AB² = 5² + w²
Thus, AB = √25+w²
Thus, the distance between the two corners is √25+w²
