Answer:
We know, 1 lbs = 0.45 Kg
Step-by-step explanation:
52 lbs = 0.45*52 = 23.58 Kg
If you want to multiply (2*x + 5) and (2*x - 5), you can do this using the following steps:
(2*x + 5) * (2*x - 5) = 4*x^2 - 10*x + 10*x - 25 = 4*x^2 - 25
The correct result is 4*x^2 - 25.
Answer: 
Step-by-step explanation:
<h3>
The complete exercise is: "Line segment YV of rectangle YVWX measures 24 units. What is the length of line segment YX?"</h3><h3>
The missing figure is attached.</h3>
Since the figure is a rectangle, you know that:

Notice that the segment YV divides the rectangle into two equal Right triangles.
Knowing the above, you can use the following Trigonometric Identity:

You can identify that:

Therefore, in order to find the length of the segment YX, you must substitute values into
and then you must solve for YX.
You get that this is:

Answer:
The distance of base of wire to the base of tower is 13.27 ft
Step-by-step explanation:
Given as :
The measure of wire connected between base ad antenna top = 20 ft
The wire is connected to the antenna on tower at height h = 15 ft above the ground
Let The distance of base of wire to the base of tower = x ft
Let the angle drawn on ground = Ф
Now, According to question
<u>In figure AOB</u>
Sin angle = 
i.e SinФ = 
Or, SinФ = 
Or, SinФ = 
Or, SinФ = 
or, Ф = 
∴ Ф = 48.5°
<u>Now, Again from figure</u>
Tan angle = 
i.e TanФ = 
Or, Tan 48.5° = 
Or, 1.13 = 
∴ x = 
i.e x = 13.27 feet
So, The distance of base of wire to the base of tower = x = 13.27 ft
Hence, The distance of base of wire to the base of tower is 13.27 ft Answer
