One of the legs of a right triangle measures 4 cm and its hypotenuse measures 20 cm. Find the measure of the other leg. If necessary, round to the nearest tenth.​

Respuesta :

Answer:

19.6

Step-by-step explanation:

Use [tex]a^2+b^2=c^2[/tex]  (where a and b are the legs and c is the hypotenuse)

  [tex]a^2+4^2=20^2[/tex]

 [tex]a^2+16=400[/tex]

         [tex]a^2=384[/tex]

          [tex]a=\sqrt{384}=8\sqrt{6} =19.6[/tex]
