Question

Carpenters stabilize The Wall frame a diagonal brace.the length of the brace is given by
$l = \sqrt[]{h {}^{2} } + w {}^{2}$
if the bottom of the brace is attached by 9m from the corner and the brace is 12 m long,how far up the corner post should be nailed​

Answer 1

Answer:

• see the above attachment.

• hope that helps.

Answer 2

Answer:

$\sqrt{63}$ or $3\sqrt{7}$

Step-by-step explanation:

L=H2+W2

L2=H2+W2   ∗∗∗ Square both sides of equation

L2−W2=H2   ∗∗∗ Subtract W2 from both sides

H2=L2−W2   ∗∗∗ Swap left and right sides

H=L2−W2   ∗∗∗ Take square root of both sides

H=(12)2−(9)2   ∗∗∗ Substitute 12 for L and 9 for W

H=144−81

H=63
