Given:
The figures of triangles and their mid segments.
To find:
The values of n.
Solution:
Mid-segment theorem: According to this theorem, mid segment of the triangle is a line segment that bisect the two sides of the triangle and parallel to third side, The measure of mid-segment is half of the parallel side.
9.
It is given that:
Length of mid-segment = 54
Length of parallel side = 3n
Using mid-segment theorem, we get
[tex]54=\dfrac{1}{2}(3n)[/tex]
[tex]2\times 54=3n[/tex]
[tex]108=3n[/tex]
Divide both side by 3.
[tex]\dfrac{108}{3}=n[/tex]
[tex]36=n[/tex]
Therefore, the value of n is equal to 36.
10.
It is given that:
Length of mid-segment = 4n+5
Length of parallel side = 74
Using mid-segment theorem, we get
[tex]4n+5=\dfrac{1}{2}(74)[/tex]
[tex]4n+5=37[/tex]
[tex]4n=37-5[/tex]
[tex]4n=32[/tex]
Divide both side by 4.
[tex]n=\dfrac{32}{4}[/tex]
[tex]n=8[/tex]
Therefore, the value of n is equal to 8.

Find the value of R and S
Answers
Answer:
R ≈ 17.7
S ≈ 19.0
Step-by-step explanation:
The angles of the triangle are 90, 43, and 47. Given these we can apply the law of sines.
26/sin(90) = s/sin(43), giving you 17.73195, rounding to 17.7.
26/sin90 = r/sin(47), giving you 19.01519, rounding to 19.0.

The standard form of a coordinate in the 2D plane is (x, y), we may express the y-coordinate of the given location as 4.
What is a Cartesian coordinate system?A cartesian coordinate system uses a set of three perpendicular lines from the x, y, and z axes, which are three mutually perpendicular axes, to describe the coordinate points.
We can represent a point in the cartesian coordinate system as (x, y, z).
There are three different types of cartesian coordinate systems: one-, two-, and three-dimensional.
The cylindrical and spherical coordinate systems are two other types of coordinate systems in addition to the cartesian system.
Find the value of the plotted point's y-coordinate using the information provided.
It is at latitude and longitude (2, 4). The "y" coordinate of the provided location can be written as "4". This is because the generic form of the coordinate in the two-dimensional plane is known to be represented by (x, y).
Since the standard form of a coordinate in the 2D plane is (x, y), we may express the y-coordinate of the given location as 4.

Answer:
x=8 and QNR= 63°
Step-by-step explanation:
90+8x-1+27=180
116+8x=180
8x=64
x=8
Answer:
8, m<QNR=63 degrees
Step-by-step explanation:
So, lets go over what we know:
The angle that makes up (8x-1) and 27 degrees is a right angle.
A right angle is 90 degrees.
So, to solve for angle m<QNR and for x, we must subtract and solve using 27 degrees, and (8x-1).
Lets put this into equation form:
(8x-1)+27=90
Lets subtract 27 from both sides to get the (8x-1) alone:
(8x-1)=63.
So lets stop here real quick.
We need to find angle M<QNR. This is (8x-1)
So looking at what we have solved so far, angle M<QNR must be 63 degrees.
Now, lets solve further to find out what x is:
(8x-1)=63
Lets add x to both sides to get 8x alone:
(8x)=64
We dont need the parethese, for they do not have a function, so:
8x=64
Finally, lets divide 8 from both sides so we can make 8x into just x:
x=8
So x is equal to 8.
Overall:
x = 8
Angle m<QNR = 63
Hope this helps! :)

Answer:

Step-by-step explanation:
Answer: After “4 hours” of work will the store earn $68.
Step-by-step explanation: To find the answer you plug in 4 into all values of x in the equation it looks like this y = -8(4)^2 + 64(4) - 60. Once you multiply, the numbers it turns into is y = -128 + 256 - 60. Then. Once you do all the addition and subtraction you get y = $68.

the surface area of earth is about 196.9 million square miles. The land area is about 57.5 million square miles, and the rest is water. What is the probability that a meteorite that reaches the surface of earth will hit land
Answers
Answer: 29.2%
Step-by-step explanation:
The total surface area is 196.9 million square miles and out of this, land occupies 57.5 million square miles.
The probability that a meteorite would hit land is the percentage of and out of the entire planet area:
= Land area/ Total earth surface area
= 57.5/ 196.9
= 29.2%
