Andrew needs a ladder to hang hoilday lights. His house is 24ft tall and he has a flower bef that extends 4 ft out from the side

elena-14-01-66 [18.8K]

Answer: $24.33\ ft$

Step-by-step explanation:

You need to draw a Right triangle as the one attached, where "x" is the lenght of a ladder Andrew will need to reach the top and be out of the flower bed.

You must apply the Pythagorean Theorem. This is:

$a^2=b^2+c^2$

Where "a" is the hypotenuse and "b" and "c" are the legs of the Right triangle.

If you solve for "a", you get:

$a=\sqrt{b^2+c^2}$

In this case, you can identify in the figure that:

$a=x\\\\b=24\ ft\\\\c=4\ ft$

Therefore, knowing those values, you can substitute them into $a=\sqrt{b^2+c^2}$ and then you must evaluate, in order to find the value of "x".

This is:

$x=\sqrt{(24\ ft)^2+(4\ ft)^2}\\\\x=24.33 ft$

Solve the system of equations given below.<br> -5x = y – 5<br> -2y = -x-21

irakobra [83]

Answer:

Step-by-step explanation:

$\left\{\begin{array}{ccc}-5x=y-5&\text{subtract y from both sides}\\-2y=-x-21&\text{add x to both sides}\end{array}\right\\\left\{\begin{array}{ccc}-5x-y=-5&\text{multiply both sides by (-2)}\\x-2y=-21\end{array}\right\\\underline{+\left\{\begin{array}{ccc}10x+2y=10\\x-2y=-21\end{array}\right}\qquad\text{add both sides of the equations}\\.\qquad11x=-11\qquad\text{divide both sides by 11}\\.\qquad x=-1\\\\\text{put the value of x to the first equation:}\\\\10(-1)+2y=10\\-10+2y=10\qquad\text{add 10 to both sides}\\2y=20\qquad\text{divide both sides by 2}\\y=10$
