Respuesta :
lets assume length of leg is x
then apply Pythagoras theorem[tex]a^{2}\dotplus b^{2}= c^{2}[/tex]
7^{2}\dotplus x^{2}= 14^{2}
14^{2}-7^{2}=x^{2}
\sqrt{14^{2}-7^{2}}=x
12.12=x
Step-by-step explanation:
IN THIS WE USE Pythagoras theorem[tex]a^{2}\dotplus b^{2}= c^{2}[/tex]
[tex]\dotpl7^{2}\dotplus x^{2}= 14^{2}[/tex]
