Solution :-
This triangle is a right angled triangle as we can see ∠POC, has a right angled sign. Now, we will assume the missing angle to be x, thus,
25° + 90° + x = 180° ( Angle sum property of a triangle )
115° + x = 180°
x = 180° - 115°
x = 65°
Thus, the measure of missing angle is 65°.
Hope that helps. :D

Answers
Answer:
Smith should use 900 minute plan and Jones should use 1500 minute plan
Step-by-step explanation:
There are best answers
1. Equations/Inequalities for Each Plan:
Plan A: Cost = $39.99 + 0.25 * (m - 450), m ≤ 450
Plan B: Cost = $59.99 + 0.30 * (m - 900), m ≤ 900
Plan C: Cost = $99.99 + 0.35 * (m - 1500), m ≤ 1500
2. Best Plan for Customers:
Customer Smith (750 min): Plan B ($59.99)
Customer Jones (1350 min): Plan C ($84.99)
3. For both customers, Plan B offers the best value for 750 minutes, while Plan C is optimal for 1350 minutes due to its lower cost per minute overages.
4. Plan A is the least cost-effective for both. The chosen plans reflect the importance of base minutes and overage charges.
1. Equations/Inequalities for Each Plan:
Let's denote the number of minutes used as "m."
Plan A:
Cost: $39.99 for 450 minutes, then $0.25/minute for each additional minute.
Equation: Cost = $39.99 + 0.25 * (m - 450), if m > 450
Inequality: m ≤ 450
Plan B:
Cost: $59.99 for 900 minutes, then $0.30/minute for each additional minute.
Equation: Cost = $59.99 + 0.30 * (m - 900), if m > 900
Inequality: m ≤ 900
Plan C:
Cost: $99.99 for 1500 minutes, then $0.35/minute for each additional minute.
Equation: Cost = $99.99 + 0.35 * (m - 1500), if m > 1500
Inequality: m ≤ 1500
2. Determine the Best Plan for Customers:
Let's evaluate the cost for both customers using the given plans:
Customer Smith:
Usage: 750 minutes
Plan A: Cost = $39.99 + 0.25 * (750 - 450) = $112.49
Plan B: Cost = $59.99
Plan C: Cost = $99.99
Best Plan: Plan B ($59.99)
Customer Jones:
Usage: 1350 minutes
Plan A: Cost = $39.99 + 0.25 * (1350 - 450) = $297.49
Plan B: Cost = $59.99 + 0.30 * (1350 - 900) = $374.99
Plan C: Cost = $99.99 + 0.35 * (1350 - 1500) = $84.99
Best Plan: Plan C ($84.99)
3. Explanation and Recommendation:
Customer Smith's usage of roughly 750 minutes falls within the range of Plan B's base minutes (900) and is more cost-effective with Plan B. However, for Customer Jones, who uses around 1350 minutes, Plan C offers a lower overall cost due to its higher base minutes (1500). Plan A is the least cost-effective option for both customers due to its lower base minutes and higher per-minute charges.
4. Summary for Employees:
Dear Team,
When assisting customers with choosing a cell phone plan, please consider the following options:
Plan A: $39.99 for 450 minutes, then $0.25/minute.
Plan B: $59.99 for 900 minutes, then $0.30/minute.
Plan C: $99.99 for 1500 minutes, then $0.35/minute.
For customers using around 750 minutes per month, recommend Plan B for its competitive pricing. For customers using around 1350 minutes, advise them to opt for Plan C to optimize cost efficiency. Always ensure to guide customers toward the most suitable plan based on their usage patterns.
Thank you for your dedication to excellent customer service.

Find the missing side length using the Pythagorean Theorem.
a²+6² = c²
Answers
Answer:
18
Step-by-step explanation:
Hello!
In the Pythagorean theorem, the summation of the square of the legs in a right triangle is equal to the square of the hypotenuse.
Let a and b be the legs, and c is the hypotenuse.
a² + b² = c²
In this equation, the hypotenuse is 30, and the measure of one leg is 24.
We can solve this by plugging in the values.
a² + b² = c²24² + b² = 30²576 + b² = 900324 = b²b = 18So the missing side length is 18.

Find the missing angles for every point here
Answers
In order to find the missing angles, we can see that vertically opposite angles and corresponding angles are equal.
46° + 82° + No. 4 = 180°
No. 4 = 180° - 128° = 52°
Therefore: No. 4 = No. 1 = 52° (vertically opposite angles)
What is angle?In geometry, an angle is actually known to be the figure that is created by two rays that actually meet at an end point that is common to the both rays. It is represented by the symbol: ∠.
So, we can see that:
Line a || Line b and Line c || Line d
46° = 7 (corresponding angles)
So, 46° + 82° + No. 4 = 180°
Thus, No. 4 = 180° - 128° = 52°
Therefore:
No. 4 = No. 1 = 52° (vertically opposite angles)
No. 2 = 180° - 52° = 128° (angles on a straight line)
No. 2 = No. 3 = 128° (vertically opposite angles)
No. 7 = No. 6 = 46° (vertically opposite angles)
No. 8 = 180° - 46° = 134° (angles on a straight line)
No. 8 = No. 5 = 134° (vertically opposite angles).
82° = No. 11 (vertically opposite angles)
No. 9 = 180° - 82° = 98° (angles on a straight line)
No. 9 = No. 10 = 98° (vertically opposite angles)
No. 9 = No. 15 = 98° (alternate angles)
No. 13 = No. 15 = 98° (vertically opposite angles)
No. 12 = No. 14 = 82° (vertically opposite angles)
46°= No. 17 (vertically opposite angles)
No. 18 = 180° - 46° = 134° (angles at a point)
No. 18 = No. 16 = 134° (vertically opposite angles)
No. 19 = 180° - (46° + 82°) = 52° (sum of angles in a triangle)
No. 19 = No. 22 = 52° (vertically opposite angles)
No. 20 = 180° - 52° = 128° (angles on a straight line).
No. 20 = No. 21 = 128° (vertically opposite angles)
No. 25 = No. 2 = 128° (corresponding angles)
No. 25 = No. 24 = 128° (vertically opposite angles)
No. 23 = No. 26° (vertically opposite angles).
So, all the angles are:
1= 52°
2= 128°

Shape of the quilt pattern = A regular hexagon
Coordinates of point A = A(4, 0)
Coordinates of point D = D(-4, 0)
Required;
The area of the hexagon
Solution;
The coordinates of the center of the hexagon, P = (0, 0)
A regular hexagon consist of six equilateral triangles.
The length of a side of the triangle = PA
Length of PA = 4 - 0 = 4
Therefore;
Length of a side of the triangle = 4
Height of the triangle = PA × sin(60)
Which gives;
Height of the triangle = 4 × (√3)/2 = 2•√3
Area of one triangle = (4 ÷ 2) × 2•√3 = 4•√2
Area of the 6 triangles is therefore;
A = 6 × 4•√2 = 24•√2
Area of the 6 triangles = Area of the hexagon

Step-by-step explanation:
first I figured out the number of years between 1990 and 2014.I basicly just subtracted 1990 from 2014 then times it by 2.85 the added 30.52
The cost in billions of dollars in 2014 would be 98.92
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
We are given that national cost C in billions of dollars for dental services can be modeled by the linear equation c=2.85n+30.52, where n is the number of years since 1990.
Then c=2.85n+30.52
Solving then subtracted 1990 from 2014
2014 - 1990
= 24
Now
c = 2.85 (24) +30.52
c = 68.4 +30.52
c = 98.92
Hence, the cost in billions of dollars in 2014 would be 98.92
