To calculate the elevation at the bottom of Lake Segundo, we need to know the elevation of the lake's surface.
However, since the question doesn't provide this information, let’s assume the surface elevation of both lakes is the same for the sake of this problem. If we assume that the elevation at the surface of Lake Profondo is at sea level (0 feet), then:
- Depth of Lake Profondo: 84 feet
- Lake Segundo: 56 feet
If Lake Profondo's surface is at 0 feet elevation, the bottom of Lake Profondo would be at:
\[ 0 - 84 = -84 \text{ feet} \]
Then, the bottom of Lake Segundo would be:
\[ 0 - 56 = -56 \text{ feet} \]
Thus, if both lakes have their surfaces at the same elevation (which we assumed as sea level), the elevation at the bottom of Lake Segundo would be -56 feet.
If the surface elevation of the lakes is known, simply subtract the depth from that elevation to find the elevation at the bottom of Lake Segundo.
