9966 [12]

Step-by-step explanation:

step 1. This is a right triangle where a^2 + b^2 = c^2 (c is the hypotenuse).

step 2. a^2 + 6^2 = 8^2.

step 3. a^2 = 64 - 36.

step 4. a^2 = 28.

step 5. a (the ladder height along the wall) = sqrt (28) where sqrt is the square root.

step 6. sqrt(28) = 2(sqrt(7)).

What are the theorems I feel like I got at least 1 wrong already ╥﹏╥

OLEGan [10]

$\begin{gathered} m\angle2=m\angle6\text{ are corresponding angles} \\ \angle2\cong\angle6\text{ are the same because the both angles are corresponding} \end{gathered}$ $\begin{gathered} m\angle2+m\angle3=180\text{ are angles on a straight line.} \\ \text{angles on straight line =180 degree} \end{gathered}$ $\begin{gathered} m\angle3+m\angle6=180\text{ are supplementary angles} \\ \text{supplementary angles = 180 degree} \end{gathered}$ $\begin{gathered} m\angle2+m\angle3=m\angle3+m\angle6 \\ angles\text{ on a straight line(180 degree)=supplementary angles(180 degree)} \end{gathered}$
