Pls help I need help

Answer 1

∴ 2nd equation can be used to determine the length of other leg.

Which is known as
`a=\sqrt{13^(2)-12^(2)}`

Explanation:

Given,

A Right Triangle has hypotenuse of
`13` units and one leg has
`12` units.

We know Pythagoras Formula for Right Triangle;

`Hypotenuse^(2) =Perpendicular^(2) +Base^(2)`

Here hypotenuse and one leg values in above equation and take
`Base=a`;

`13^(2) =12^(2) +a^(2)`

`a^(2) =13^(2) -12^(2)`

`a=\sqrt{13^(2)-12^(2)}`

So 2nd equation can be used to determine the length of other leg.
