Since this is a right triangle, we can use the Pythagorean Theorem to help us.
[tex](length-of-leg1)^2+(length-of-leg2)^2 = (length-of-hypotenuse)^2\\[/tex]
Known information:
- one leg's length: 7 cm
- hypotenuse's length: 25cm
Now let's plug the known information into the equation:
[tex]7^2 + (length-of-leg2)^2=25^2\\(length-of-leg2)^2 = 25^2-7^2\\\\(length-of-leg2)^2 = 576\\\\length-of-leg2=24[/tex]
Thus the length of the other leg is 24cm.
Hope it helps!
