Answer:
x=144
Step-by-step explanation:
Step 1- Find the sum of degrees in the polygon using the equation below. n=number of sides in the polygon
(n-2)180
(8-2)180=6(180)= 1080
Step 2-Subtract the angles provided to find x
1080-129-132-136-124-141-158-116=144
The value of x in the octagon is given by the equation x = 144°
What is the sum of the interior angles of a polygon?The sum of the interior angles of a polygon is given by the formula
Sum of Interior angles of a polygon with n sides is
nθ = 180° ( n - 2 )
where n is the number of sides
θ = angle in degrees
Given data ,
Let the number of sides of the polygon be represented as n
The value of n = 8
So , the sum of the interior angles of an octagon is given by
nθ = 180° ( n - 2 )
Substituting the values in the equation , we get
nθ = 180° ( 8 - 2 )
nθ = 180° x 6
nθ = 1080°
Now , the angles in the octagon = { x , 124° , 141° , 158° , 116° , 129° , 132° , 136° }
Sum of the interior angles of an octagon A = 1080°
Substituting the values in the equation , we get
x + 124° + 141° + 158° + 116° + 129° + 132° + 136° = 1080°
x + 936° = 1080°
x = 144°
Therefore , the value of x is 144°
Hence , the value of x from the polygon is 147°

QUESTION 4:
The area of the figure is 40 units²
QUESTION 5
The area of the compost shape is 40 in.²
Step-by-step explanation:
QUESTION 2.
The area of the polygon is given as follows;
The area of two triangles + The area of trapezoid
1/2×6×3 + 1/2×3×4 + 1/2×(6 + 7) = 21.5 units²
QUESTION 3
The diameter of the semicircle, 'd', is given as follows;
d = √(8² + 3²) = √73
The area of the semicircle = π·d²/4 = π·73/4 = 18.25·π unit²
The area of the right triangle beside the semicircle is given as follows;
1/2 × 8 × 3 = 12 unit²
The area of the combined figure = The area of the semicircle + The area of the right triangle
∴ The area of the combined figure = 12 + 18.25·π units²
QUESTION 4:
The dimensions of the parallelogram are;
Width, W = √(4² + 1²) = √(17)
Length, L = √(8² + 2²) = √(68)
The area of the parallelogram, [tex]A_R[/tex] = W × L = √(17) × √(68) = √(17 × 68) = 34
The area of the parallelogram, [tex]A_R[/tex] = 34 units²
The length of a parallel side, 'A', of the parallelogram is A = 6
The height of the parallelogram, is h = 1
The area of the parallelogram is A = B·h = 6 × 1 = 6 units²
The area of the figure is the sum of the area of the rectangle and the area of the parallelogram
Therefore, we have;
The area of the figure = 34 units² + 6 units² = 40 units²
QUESTION 5
The composite shape consists of a triangle and a rectangle
Therefore, we have;
The area of the rectangle = 5 in. × 7 in. = 35 in.²
The area of the triangle = 1/2 × 2 in. × 5 in. = 5 in.²
The area of the compost shape = The area of the rectangle + The area of the triangle
∴ The area of the compost shape = 35 in.² + 5 in.² = 40 in.²
The area of the compost shape = 40 in.².

The number of bagels and coffee sold by a bagel shop yesterday can be modeled using the equation b+c=84. Their sales for the same day can be modeled using the equation 2b+c=145. Solve this system of equations using substitution. How many bagels and coffee were sold
Answers
Answer:
There were 61 bagels and 23 coffee sold
Step-by-step explanation:
Let us solve the question
∵ The number of bagels and coffee sold by a bagel shop yesterday
can be modeled using the equation b + c = 84
∴ b + c = 84 ⇒ (1)
∵ Their sales for the same day can be modeled using the equation
2b + c = 145
∴ 2b + c = 145 ⇒ (2)
Let us solve the system of equations using substitution
→ Subtract the two sides of equation (1) by b to find c in terms of b
∵ b - b + c = 84 - b
∴ c = 84 - b ⇒ (3)
→ Substitute c in equation (2) by equation (3)
∵ 2b + 84 - b = 145
→ Add the like terms on the left side
∴ (2b - b) + 84 = 145
∴ b + 84 = 145
→ Subtract 84 from both sides
∵ b + 84 - 84 = 145 - 84
∴ b = 61
→ Substitute the value of b in equation (3) to find c
∵ c = 84 - 61
∴ c = 23
∴ There were 61 bagels and 23 coffee sold.

Answer:
x= -8
Step-by-step explanation:
First distribute: 3(2x+3)-x is equal to 6x+9-x, or 5x+9
Rewrite: 5x+9=x-23
Add 23 to both sides to get rid of it on one: 5x+32=x
Subtract 5x from both sides to get rid of it on one: 32= -4x
Divide by -4: -8=x
Answer:
x = -8
Step-by-step explanation:
[tex]3(2x + 3) - x = x - 23[/tex]
➡️ [tex]6x + 9 - x = x - 23[/tex]
➡️ [tex]5x + 9 = x - 23[/tex]
➡️ [tex]5x - x = - 23 - 9[/tex]
➡️ [tex]4x = - 32[/tex]
➡️ [tex]x = - 8[/tex] ✅

Part II: Find the angle O in radians, (2 points)
Answers
The circle has radius 6 feet, so its total circumference is 2π • (6 ft) = 12π ft.
As an arc, the complete circle corresponds to a central angle of 2π radians. So the red arc corresponds to a central angle θ such that
θ / (15 ft) = (2π rad) / (12π ft)
Then
θ = (15 ft) • (2π rad) / (12π ft) = 15/6 rad = 2.5 rad
