Jaxon is building a brace for a wall shelf. It is in the shape of a right triangle. He has cut one leg to be 18 inches long and the other leg to be 2 feet long. How many inches long must the last piece of lumber be?

Respuesta :

30 inches or 2.5 feet

Answer:  The length of last piece is 30 inches.

Step-by-step explanation:

Since we have given that

Length of one leg = 18 inches

Length of other leg = 2 feet = 24 inches

As it is in the right triangle.

[tex]H^2=P^2+B^2\\\\H^2=18^2+24^2\\\\H^2=900\\\\H=\sqrt{900}\\\\H=30[/tex]

Hence, the length of last piece is 30 inches.
