The ocean surface is at 0 ft elevation. a diver is underwater at a depth of 138 ft. in this area, the ocean floor has a depth of 247 ft. a rock formation rises to a peak 171 ft above the ocean floor. how many feet below the top of the rock formation is the diver? i want to know how you would work this out.

We know that the ocean floor has a depth of 247 feet, and we also know that the diver is underwater at depth of 138 ft, so its distance from the ocean floor will be:

feet

Now, the rock formations rises to a peak 171 to above the ocean floor, so to find how many feet below the top of the rock formations is the diver, we are going to subtract the distance to the driver form the ocean floor from the rock formations height:

feet

We can conclude that the diver is 62 feet below the top of the rock formations.

hope it helps

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
