Use similar triangles and a proportion to find the length of the lake shown here.
(Hint: The side 92 m long in the smaller triangle corresponds to side of 92 m + 112 m = 204 m in the larger triangle.)
N= m
Answer: n = 152 m
Step-by-step explanation:
write a proportion to find n.
46/n = 92/204
n = 102 m
The length of the lake shown in the provided image using similar triangles and a proportion is 102 meters.
What is similar triangle's proportion property?In the two similar triangle, the ratio of two sides of one triangle is equal to the ratio of corresponding sides of the other triangle.
In the figure shown,
The length of the base of the smaller triangle is 92 meters, The height of this triangle is 46 meters.The total length of the base of the larger triangle is,
[tex]112+92=204\rm\; m[/tex]
The height of this triangle is n meters, which is equal to the length of lack. Thus, by the similar triangle proportion property,
[tex]\dfrac{n}{204}=\dfrac{46}{92}\\n=\dfrac{46\times204}{92}\\n=120\rm\; meters[/tex]
Thus, the length of the lake shown in the provided image using similar triangles and a proportion is 102 meters.

Answer:
a) NT = 8
b) RS = 8
c) RT = 16
d) ZR = 24
Step-by-step explanation:
All of the marked sides are congruent. (That's what the marks mean.) It might help you to put 8 next to each hash mark like it is on NS. So, you have ...
NT = RS = ST = TZ = NS = 8
Segments on the same line sum, so ...
RT = RS +ST = 2RS = 16
ZR = RS +ST +TZ = 3RS = 24
a) NT = 8
b) RS = 8
c) RT = 16
d) ZR = 24
In parallelogram DEFG DH=x+2 HF=2y GH=3x-3 and HE=5y+1. Find the values of x and y.
Answer:
y = 10 and x =18
Step-by-step explanation:
From the parallelogram,
DH + HF = DF
x+2 + 2y = DF
Also DH = HF
x+2 = 2y
x - 2y = -2 .... 1
Also GH = HE
3x-3 = 5y+1
3x - 5y = 1 + 3
3x-5y = 4 .... 2
Solve 1 and 2 simultaneously
x - 2y = -2 .... 1 * 3
3x-5y = 4 .... 2 * 1
_____________
3x-6y = -6
3x-5y = 4
Subtract
-6y + 5y = -6-4
-y = -10
y = 10
Substitute y = 10 into 1
x- 2y = -2
x - 2(10) = -2
x - 20 = -2
x = -2+20
x = 18
Hence y = 10 and x =18
5) If Oskar bisects the diameter of a circle, what is he trying to construct?
6) What is the center and radius of a circle with the equation (x - 5)+ (y + 3)2 = 49
Answer:
Center = (5,-3) and radius = 7
Step-by-step explanation:
(5) If Oskar bisects the diameter of a circle, what is he trying to construct the radius of the circle.
(6) The given equation is :
[tex](x-5)^2+(y+3)^2=49[/tex]
The general equation of circle is given by :
[tex](x-a)^2+(y-b)^2=r^2[/tex] ...(1)
Where
(a,b) are the coordinates of the centre and r is the radius.
The given equation can be written as :
[tex](x-5)^2+(y+3)^2=7^2[/tex] ..(2)
Comparing equation (1) and (2) we get :
a = 5, b = -3 and r = 7
So,
Center = (5,-3) and radius = 7
Hence, this is the required solution.

Two dot plots are shown one below the other. The title for the top dot plot is Sixth Graders and the title for the bottom plot is Seventh Graders. Below the line for each dot plot is written Height followed by inches in parentheses. There are markings from 52 to 57 on the top line and the bottom line at intervals of one. For the top line there are 2 dots above the first mark, 1 dot above the second mark, 1 dot above the third mark and 2 dots above the fourth mark. For the bottom line, there are 2 dots for the fifth mark, there are 4 dots above the sixth mark.

Select the procedure that can be used to show the converse of the Pythagorean theorem using side lengths chosen from 5 cm, 8 cm, 12 cm, and 13 cm.
O A. Knowing that 52 + 122 = 13^2, draw the 5 cm side and the 12 cm side with a right angle between them. The 13 cm side will fit to form a right triangle.
O B. Knowing that 52 + 122 = 13^2, draw any two of the sides with a right angle between them. The third side will fit to form a right triangle.
O C. Knowing that 52 + 82 = (slash in the eqaul sign) 12^2, draw the 5 cm side and the 8 cm side with a right angle between them. The 12 cm side will fit to form a right triangle.
D. Knowing that 82 + 122 > 13^2, draw the 8 cm side and the 12 cm side with a right angle between them. The 13 cm side will fit to form a right triangle.
Answer: Choice A.
Knowing that 5^2 + 12^2 = 13^2, draw the 5 cm side and the 12 cm side with a right angle between them. The 13 cm side will fit to form a right triangle.
The diagram is shown below.
The converse of the pythagorean theorem states that if a^2+b^2 = c^2, then we have a right triangle with hypotenuse c. The hypotenuse is always the longest side and always opposite the 90 degree angle.
Note how 5^2+12^2 = 25+144 = 169 while 13^2 = 169, so that shows how 5^2+12^2 = 13^2 is true.

Christopher went into a restaurant and bought 5 hamburgers and 10 drinks, costing a total of $52.50. Wyatt went into the same restaurant and bought 2 hamburgers and 9 drinks, costing a total of $31. Write a system of equations that could be used to determine the price of each hamburger and the price of each drink. Define the variables that you use to write the system.
Answer:
Step-by-step explanation:
Let the price of each hamburger be a and the price of drink each be b.
5a+10b=52.50
2a+9b=31
5a+10b=52.50
a=10.5-b
2(10.5-b)+9b=31
7b=10.5
b=1.5
a=10.5-1.5
a.9
∴The price of each hamburger is $9 and the price of each drink is $1.5

What are trigonometric relations?
Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
tan θ = sin θ / cos θ
cosec θ = 1/sin θ
sec θ = 1/cos θ
cot θ = 1/tan θ
Given data ,
Let the triangle be ΔPQR
Let the angle ∠P = θ
Triangle ΔPQR is a right angle triangle
where ∠Q = 90°
Now , the value of the sides are
PQ = 8 cm
QR = 15 cm
PR = 17 cm
Now , from the trigonometric relations
∠QPR = θ
tan θ = opposite side / adjacent side
Opposite side of Triangle PQR is QR
Adjacent side of Triangle PQR is PQ
So , substituting the values in the equation , we get
tan θ = opposite side / adjacent side
tan θ = QR / PQ
tan θ = 15 / 8
tan θ = 1.875
Now , the value of θ is
The value of θ = tan⁻¹ ( 1.875 )
The value of θ = 61.93°
Therefore , the value of θ is 61.93°
Hence , The value of angle P of the triangle ΔPQR is ∠P = 61.93°
