we are going to times the both sides by two

This is what is in the middle of the second paragraph. That statement is correct.
I don't know that it is any simpler or not, but what they have done in the answer is rationalize the denominator. That means that the denominator is no longer under the square root sign.
To get that result, you multiply numerator and denominator by √F
When you do that, your get

This results in the middle answer.

Answer:
-40
Step-by-step explanation:
multiplie then go your self cause you mdkdj you cant do math hahahhaha
The height of the ladder on the building is 19.77 feet
<h3>How high does the ladder reach on the building?</h3>
Represent the height of the ladder on the building with h
So, the given parameters are:
Angle, x = 64 degrees
Length of ladder, l = 22 feet
The height of the ladder on the building is calculated using
sin(x) = h/l
Substitute the known values in the above equation
sin(64) = h/22
Multiply both sides by 22
h = 22 * sin(64)
Evaluate the product
h = 19.77
Hence, the height of the ladder on the building is 19.77 feet

Reflection is the way of projecting a mirror figure to the other side of the axis of symmetry. When reflection is done, like what we can observe in the mirrors, the properties that can be observed are parallelism, colinearity and angle measure. Orientation is not preserved. Answer is C
