Answer:

Step-by-step explanation:
Use the Pythagorean Theorem

and
are either opposite or adjacent
is the hypotenuse.
1. Look for the right angle. (the little box). The right angle "points" to the hypotenuse. In this case, the hypotenuse is 25.
2. Because we know the hypotenuse is 25. We know that 24 is our adjacent. Meaning our missing side is the opposite.
3. Plug in the numbers. 
4. Solve:

Answer:
2,796.
Step-by-step explanation:

Answer:
C
Step-by-step explanation:
Formula for potential energy is PE = m*g*h
where
m is the mass, in kg
g is the acceleration due to gravity, in meters per second squared, and
h is the height, in meters
The problem gives m = 50, g = 9.8, and h = 5. We plug that into the formula and get out answer. So:

Correct answer is C.
