The gable end of the roof shown is divided in half by a vertical brace. Find the distance h (in ft) from an eave to the peak. 41
nlexa [21]

Answer:

h = 9 ft  

Step-by-step explanation:

Assume the diagram is like the one below.

∆ABD is a right triangle.

We can use Pythagoras' Theorem to find the height h.

\begin{array}{rcl}h^{2} + 40^{2} & = & 41^{2}\\h^{2} + 1600 & = & 1681\\h^{2} & = & 1681 - 1600\\& = &81\\h& = & \sqrt{81}\\&=& \mathbf{9}\end{array}\\\text{The height of the gable is $\large \boxed{\textbf{9 ft}}$}

Can you help me with 12-3(x+1)=30
inysia [295]
Greetings!

12-3(x+1)=30
Distribute the Parenthesis.
12-3x-3=30
Combine like terms.
9-3x=30
Add -9 to both sides.
(15-3x)+(-9)=(30)+(-9)
-3x=21
Divide both sides by -3.
(-3x)/-3=(21)/-3
The Answer Is:
x=-7

Hope this helps.
