8. The two triangles are congruent as suggested by their appearance. Find the value of all the variables. The
diagrams are not to scale.
Steps would be extremely appreciated (20 points)
Answer: d is 53 degrees, c is 5, g is 13, e is 90 degrees, f is 37 degrees, b is 12 .
Step-by-step explanation:
Since they're congruent you just compare the two and replace them. You have the answers on both sides, they're just split up. So look at one side, then the other, and see what you can find. Repeat.
Answer and Step-by-step explanation:
Since the triangles are congruent, that means all the variables correspond to the values of the other triangle, and vise versa.
g = 13
b = 12
f = 37
a = 90
c = 5
d = 53

recursive formula for 3,5,7,9,11
Answer:
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 2
Step-by-step explanation:
There is a common difference d between consecutive terms
d = 5 - 3 = 7 - 5 = 9 - 7 = 11 - 9 = 2
A recursive formula allows a term in the sequence be found by adding d to the previous term, then
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 2 : with a₁ = 3
The graph represents the piecewise function. I need to find the function.
Answer:
i am sorry i can not see it
Step-by-step explanation:
How would you graph a line through the point (-2, -5), with a slope of 2/7? Be specific.
First, you would plot the point (-2,-5). The next part requires an understanding of what slope is. My teacher told me slope was "rise over run." Basically, the numerator is how much the value of y increases when x increases by the number that's in the denominator. What that means is, when you add 7 to the x value, you add 2 to the y value. You can use this to find another point to graph.
(-2+7,-5+2)
=(5,3)
You can plot this point and draw a line through both points, and you're finished.
Another thing could do is draw a slope triangle. Draw a line (segment) from (-2,-5) for 7 units in the direction of the x-axis. Draw a line (again, a segment, really. We have to be technical xD) from where that segment ends for 2 units in the direction of the y-axis. Plot a point where that ends, and it should be (5,3). Draw a line through (5,3) and (-2,5), and you're done.
Hope I could help you!

Work out the area of the triangle. 13m 12m and 5m
Answer:
30m²
Step-by-step explanation:
To find the area of a triangle, you need to ensure that the triangle is a right-angled triangle. We can use the Pythagoras Theorem to help us prove that.
a² + b² = c²
5² + 12² = 169
13² = 169
By converse of Pythagoras Theorem, the triangle is a right-angled triangle.
Thus, you can directly find the area of the triangle using the formula: base × height ÷ 2.
Area = 12 × 5 ÷ 2
= 30m²
We can use the formular-

to relate a ball's surface area S (in square Inches) to its radius r (in inches). Suppose a ball has a surface area of 226.8
square Inches. What is its radius?
Round your answer to the nearest tenth
Answer:
r = 4.24 inches
Step-by-step explanation:
Given that,
The surface area of the ball, A = 226.8 sq inches
The formula for the surface area of a sphere is given by :
[tex]A=4\pi r^2[/tex]
Where
r is the radius of the ball
[tex]r=\sqrt{\dfrac{A}{4\pi}} \\\\r=\sqrt{\dfrac{226.8}{4\pi}} \\\\r=4.24\ inch[/tex]
So, the radius of the ball is 4.24 inches.

Find the volume of a pyramid with a square base, where the perimeter of the base is 6.9 cm and the height of the pyramid is 6.4 cm. Round your answer to the nearest tenth of a cubic centimeter
Answer:
6.3 cm^3
Step-by-step explanation:
volume of a pyramid = 1/3(length x width x height)
perimeter of a square = 4 x length
6.9 = 4 x length
length = 6.9 /4 = 1.725
Volume = 1/3 x (1.725 x 1.725 x 6.4) = 6.348
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero

Answer:
Step-by-step explanation:
point-slope equation looks like y-y1 = m(x-x1)
plug in the given point for x and y.... and the slope for m
y-9 = 3/2(x-6)
y-9 = 3/2x - 9

Which graph shows the solution to this system of equations?
Answer:
the first graph
Step-by-step explanation:
change the two equations into the slop-intercept form: y = mx + b
=> y = 6 + x/5 => y = 1/5 x + 6 slope↑ ↑y-intercept
=> x = y/6 - 5 => 6x = y - 30 => y = 6x + 30
find the line with y-intercept = 6, slope = 1/5 and the other line with y-intercept = 30, slope = 6

Answer:
175.2 square feet
Step-by-step explanation:
The lateral area is the total area of the side faces. It excludes the area of the top and bottom "bases" of the prism.
It can be found by adding the areas of the four rectangles. The two you can't see have the same areas as the two you can see.
Since the height of each rectangle is 4 feet. the total area will be the product of that and the perimeter of the prism.
LA = Ph . . . . perimeter times height
LA = 2(L+W)h . . . . the perimeter is twice the sum of length and width
LA = 2(12.3 ft + 9.6 ft)(4 ft) = 2(21.9 ft)(4 ft) = 175.2 ft²
The lateral area of the prism is 175.2 ft².
__
The attachment shows scribbling on two of the faces that contribute to the lateral area. As stated above, the other two faces are the same size as these.

The slant height of the cone is 5.6km, the total surface area is 50.4πkm, the lateral surface area is 16.8π km.
What is a cone?A cone is a three-dimensional geometric shape with a smooth and curving surface and a flat base, with an increase in the height radius of a cone decreases to a certain point.
The volume of a cone is (1/3)πr²h.
The total surface area of a cone is πr(r + l).
The curved surface area is πrl.
In the given question radius of the cone is (6/2) km = 3 km.
The slant height of the cone is 5.6 km.
The total surface area of the cone is = π×3(3 + 5.6) km.
= 3π(16.8) km.
= 50.4π km.
lateral surface area is = π×3×5.6 km.
= 16.8π km.

Answer:
32π + 96 [tex]cm^{2}[/tex] = exact area
196.48 [tex]cm^{2}[/tex] = area to the nearest 100th
Step-by-step explanation:
Area of semicircle = 1/2π[tex]r^{2}[/tex] = 1/2π[tex]8^{2}[/tex] = 1/2π(64) = 32π
Area of triangle = 1/2bh = 1/2(16)(12) = 96
Total area = 32π + 96 [tex]cm^{2}[/tex]
or 100.48 + 96 = 196.48 [tex]cm^{2}[/tex]
32π + 96 cm² = exact area
196.48 cm² = area to the nearest 100th
What is a semi-circle?A semicircle is a one-dimensional locus of points that makes up one half of a circle in mathematics. A semicircle's whole arc is always 180 degrees long. It just has one symmetry line.
Given
Area of semicircle = 1/2πr² = 1/2π(8)² = 1/2π(64) = 32π
Area of triangle = 1/2bh = 1/2(16)(12) = 96
Total area = 32π + 96 cm²
or 100.48 + 96 = 196.48 cm²
