Hello!
If you add up the squares of the two legs, it will equal the square of the hypotenuse. As we already have the hypotenuse, we will subtract.
225-81=144
Now we find the square root.
√144=12
Therefore, the other leg is 12 cm long.
I hope this helps!
if we take 260 to be the 100%, what is 52 off of it as a percentage?

Not sure about the statement
movement down 5 units
move right 2 units
