Answer:
∴ 2nd equation can be used to determine the length of other leg.
Which is known as 
Step-by-step explanation:
Given,
A Right Triangle has hypotenuse of 
units and one leg has 
units.
We know Pythagoras Formula for Right Triangle;
Here hypotenuse and one leg values in above equation and take 
;
So 2nd equation can be used to determine the length of other leg.
