Answer:
this is the correct graph
Answer:
0.87
Step-by-step explanation:
The lengths of the two segments below then tell whether they are congruent
YZ = 4
XW = 12
not congruent
This is further explained below.
<h3>What is a number line?</h3>
Generally, A number line is a depiction of a graded straight line that serves as an abstraction for real numbers, which are symbolized by the
Number lines are used in introductory mathematics. It is generally accepted that a real number may be assigned to each point on a number line and that each point can be assigned to a real number.
YZ = Z - Y = 1 -(-3) = 4
XW = W -X = 5 -(-7) = 12
Because the segments are not the same length, they cannot be considered congruent.
In conclusion, It is self-evident that segment YZ will not have the same length as segment XW since it is just a portion of the latter.

In a 30 - 60 - 90 triangle the side opposite the hypotenuse is 1/2 the hypotenuse and which will be the shorter side. Read this over a couple of times till you realize that (x + 12)/2 is the shortest side.
[(x + 12) / 2]^2 + x^2 = (x + 12)^2 subtract [(x + 12)/2]^2 from both sides.
x^2 = (x +12)^2 - [ (x +12)/2]^2
x^2 = (x + 12)^2 [ 1 - (1/2)^2] You were given this as a question in school? It seems awfully hard.
x^2 = (x + 12)^2 [3/4]
4x^2 = 3*(x^2 + 24x + 144)
4x^2 = 3x^2 + 72x + 432
x^2 - 72x - 432 = 0 This is a quadratic, do you know what they are?
The solution to this comes to x = 77.56
I don't think I made a mistake, but it is sure possible.Check the numbers and my method.
