Answer:
x=8.5
Step-by-step explanation:
∠AOC=68
∠COD= (2x+5)
∠AOC and ∠COD are complimentary angles. This means that when you add them together you get 90.
∠AOC + ∠COD = 90
68 + (2x+5) =90
2x+5=22
2x=17
x=8.5

12. What is the sum of the interior angles for a pentagon? (1 point)
900
540°
720°
108°
Answers
Answer:
540°
Step-by-step explanation:
Consider a regular pentagon. Divide it radially into five congruent, isosceles triangles. Each triangle has a vertex angle of 360°/5 = 72°, and base angles of (180°-72°)/2 = 54° each.
An interior angle of the pentagon is made up of two of those 54° angles, so interior angle = 108°.
Sum of interior angles = 5·108° = 540°

Shring's dining room table is round and has a radius of 4.5 feet. What is the tabletop's are ?
Answers
Answer:
Step-by-step explanation:
Radius 4.5 feet what’s is the tabletop area
The area of the table top is 63.62 square feet.
What is area in geometry?
'In geometry, the area can be defined as the space occupied by a flat shape or the surface of an object.'
According to the given problem,
Radius of the table = 4.5 feet
Since, the table is round,
Area of a circle = [tex]\pi r^{2}[/tex]
= π × 4.5 × 4.5
= 63.617
Hence, we can conclude, the area of the table-top is 63.62 square feet.

The value of a collectible toy is increasing exponentially. The two points on the graph
show the toy's initial value and its value 3 weeks afterward.
Answers
The question is incomplete. Here is the complete question.
Part A
The value of a collectible toy is increasing exponentially. The two points on the graph show the toy's initial value and its value 3 weeks afterward.
Express the toy's value t, in dollars, as a function of time w in weeks after purchase.
Part B
Write an expression to represent the toy's value 10 days after purchase
Answer and Step-by-step explanation: An exponential function is of the form: [tex]y=ab^{x}[/tex]
Part A
Translating to the question, the toy's value as a function of time is
[tex]t=ab^{w}[/tex]
To determine constants a and b, we use points given by graph.
First, (0,5) to find a:
[tex]5=a.b^{0}[/tex]
a = 5
Now, (3,10) to determine b:
[tex]10=5b^{3}[/tex]
[tex]b=\sqrt[3]{2}[/tex]
b = 1.26
The toy's value as a function of time in weeks is [tex]t=5.(1.26)^{w}[/tex]
Part B
Since, the function is in weeks:
1 week = 7 days
w weeks = 10 days
[tex]w = \frac{10}{7}[/tex]
Replacing w:
[tex]t=5.(1.26)^{w}[/tex]
[tex]t=5.(1.26)^{10/7}[/tex]
Expression that represents toy's value after 10 days is [tex]t=5.(1.26)^{10/7}[/tex].
