Ireceived this question as part of an online quiz:
gemma, a scuba diver, begins a dive on the side of a boat 4 feet above sea level. she descends 28 feet. which integer represents the distance that gemma is below sea level?
i gave the answer as 24 and got the question wrong. the other possible answers were -24, -32, and 32. i suspect they were looking for -24. i don't believe you can be a negative distance below sea level.
am i seeing this correctly, or can you be a negative distance below sea level?

The negative represents that the distance is below sea level

Let us assume sea level is Zero,  0.

Don't forget the boat is 4 feet above sea level. Am thinking her measurements are taken from this reference.

So if she descends 28 feet down, that would be:  4 feet from the boat and 24 feet into the water.

  +4    0    -24:      From +4 to -24 is 28 feet.
The answer is -24.  The minus is just a sign to show the reference is below the sea  level.

Okay so this is simple addition, once you know how to do it. 
The interior angles of a triangle should always add up to 180 Degrees. 

Now that you know this, all you have to do is add the numbers together and see which ones add up to 180 degrees. 

A. - 90+42+58=190
B. - 60+60+60=180
C. - 100+48+42=190
D. - 31+75+70=176

Out of these choices the only one that adds up to 180 is B. So your answer would be B.
