pls help I need help

Answer 1

Answer:

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

  Which is known as $a=\sqrt{13^{2}-12^{2}}$

Step-by-step 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.
