a) x = 9b) arc JK = 68c) arc MJ = 112d) arc LMK = 248================================
Explanation:
Arcs JK and KL form a semicircle, so they add to 180 degrees
(arcJK) + (arcKL) = 180
(5x+23) + (17x-41) = 180
22x-18 = 180
22x = 180+18
22x = 198
x = 198/22
x = 9
Then you'll use this x value to find arc JK and arc KL
arc JK = 5x+23 = 5*9+23 = 68
arc KL = 17x - 41 = 17*9-41 = 112
Since central angles MNJ and KNL are vertical angles, this means minor arcs MJ and KL are congruent arcs. So arc MJ is also 112 degrees
Arc LMK is basically nearly everything of the full circle, but we exclude out the portion from L to K (the shorter distance)
arc LMK = (full circle) - (measure of minor arc LK)
arc LMK = 360 - 112
arc LMK = 248

Answer:
a = 45
Step-by-step explanation:
The total angle of the shape is 90°
That means you should subtract 90° from 45°
90 - 45 = 45

This trapezoid represents the base of a right prism that has a surface area of 2112 square feet.
What is the height of the prism?
Enter your answer in the box.
ft
Answers
The height of the right prism of the surface area given as 2112 square feet is thrice the inverse of the perimeter (h=3/p ft).
The surface area of the right prism is 2112 sq feet.
The length of two parallel sides of the trapezoid is 31 feet and 13 feet and the height is 16 feet.
What is the surface area of the right prism?If the side edges of a prism are perpendicular to its ends or the base, it is called a right prism.
The surface area of the right prism is 2×base area+ perimeter×height
area of base or trapezoid = [tex]\rm \frac{1}{2} \times (sum \: of \: parallel \: sides) \times h[/tex]
[tex]\rm \frac{1}{2} \times (13+31) \times 16\\=352\: ft^{2}[/tex]
The surface area of the right prism = 2B ×Ph
[tex]\rm 2112 = 2\times 352+Ph\\\rm 2112 \div 704 = Ph\\[/tex]
h= 3/p ft
The height of the right prism of the surface area given as 2112 square feet is thrice the inverse of the perimeter.

Triangle Review 2.0 (Math i need help please)
Answers
Answer:
A= 30
Step-by-step explanation:
This requires several steps.
First, you need to find the 2 other missing angles.
One can be found easily by substracting 130 from 180
so 180-130 = 50
The other angle is the same as 8x+4
Now set up your equation
180=3x-6 + 8x+4 +50
180 = 3x + 8x -6 + 4 +50
180+6-4-50 = 11x
132 = 11x
132/11 = x
12 = x
Now plug in 12 for x in your angle A
A=3x-6
A=3 * 12 - 6
A=36 - 6
A= 30

S = 15.47 units
Step-by-step explanation:
First, convert the degree angle into radians:
68° × (π/180) = 1.19 rad = theta
The arc length S is given by
S = r × theta
= (13 units)(1.19 rad)
= 15.47 units
Answer:
15.43
Step-by-step explanation:
The formula = angle / 360 × circumference
= angle / 360 × pi diameter
= 68 / 360 × pi × 13 + 13
= 68 / 360 × pi × 26
= 17 / 19 × pi × 26
= 221 / 45 pi
= 15.43

Find the area of the figure below. Show all your work.

Answers
Answer:
[tex]143.8\:\mathrm{ft^2}[/tex]
Step-by-step explanation:
The composite figure shown in the picture consists of a semi-circle and a trapezoid. We can even break this trapezoid into a rectangle and two triangles for even simpler calculations. We can find the total area of the figure by simply adding the total area of the shapes we will break the figure into:
Area of semi-circle (half the area of a circle): [tex]\frac{1}{2}\cdot 4.5^2\cdot \pi[/tex]
Area of trapezoid (average of bases multiplied by height): [tex]16\cdot 7[/tex]
Thus, the total area of the figure is:
[tex]\frac{1}{2}\cdot 4.5^2\cdot \pi+16\cdot 7=143.808625618\approx \boxed{143.8\:\mathrm{ft^2}}[/tex]
