26 ft
24 ft
The height each brace reaches vertically is
(Simplify your answer.)

Respuesta :

Answer:

The height each brace reaches vertically is 10 feet

Step-by-step explanation:

Let

h -----> the height each brace reaches vertically in feet

d ----> the diagonal braces in feet

x ----> the horizontal distance in feet

Applying the Pythagoras Theorem

[tex]d^2=h^2+x^2[/tex]

we have

[tex]d=26\ ft\\x=24\ ft[/tex]

substitute

[tex]26^2=h^2+24^2[/tex]

Solve for h

[tex]h^2=26^2-24^2[/tex]

[tex]h^2=100[/tex]

[tex]h=10\ ft[/tex]

therefore

The height each brace reaches vertically is 10 feet
