96-49=47 feet
if the diver swam 96 feet deep...then goes up 49 feet....that means his distance below the lake reduced hence you subtract
Answer: 12
Step-by-step explanation:
<em>Although you have not included which value is the hypotenuse or if they are legs, I will assume the hypotenuse is 20, due to the triangle appearing to be a multiple of the standard 3-4-5 triangle.</em>
The pythagorean theorem is a^2+b^2=c^2, where a and b are the legs and c is the hypotenuse. Thus, plug in the values to get:




I think it's B. Distance hope this was right
