What is the Exterior Angle?Exterior Angle is defined as an angle produced on the outside of a polygon by extending the sides of the polygon.
To determine the measure of an Exterior angle of a polygon:
First, we have to find the measure of the supplemental interior angle
Then write the equation: Int. + ext. = 180
Here take an interior angle = 93°, find its Exterior angle
⇒ 93 + ext. = 180 ⇒ ext. = 180 - 93 = 87°
Since the sum of all exterior angles of a convex polygon = 360°
As per the given figure,
⇒ x° + 52° + 87° + (x+3)° + 78° = 360°
Combine the likewise terms to get,
⇒ 2x + 220 = 360
⇒ 2x = 360 - 220
⇒ 2x = 140
⇒ x = 70
Therefore, the value of x would be 70°.

A dietician is planning a snack package of fruit and nuts. Each ounce of fruit will supply zero units of protein, 3 units of carbohydrates, and 2 unit of fat, and will contain 40 calories. Each ounce of nuts will supply 3 units of protein, 2 unit of carbohydrate, and 4 units of fat, and will contain 50 calories. Every package must provide at least 6 units of protein, at least 10 units of carbohydrates, and no more than 16 units of fat. Find the number of ounces of fruit and number of ounces of nuts that will meet the requirement with the least number of calories. What is the least number of calories?
Answers
Using a system of inequalities, it is found that:
The quantities that will meet the requirement with the least number of calories is: 2 ounces of fruit and 3 ounces of nuts.The least number of calories is: 230 calories.System of inequalitiesThe variables to the system of inequalities are given as follows:
Variable x: number of ounces of fruit.Variable y: number of ounces of nuts.At least 6 units of protein are needed, hence, considering the amount of protein or each snack, the inequality is:
3y ≥ 6
y ≥ 2.
At least 10 units of carbohydrates are needed, hence, considering the amount of carbohydrates of each snack, the inequality is:
3x + 2y ≥ 10.
At least 16 units of fat are needed, hence, considering the amount of fats of each snack, the inequality is:
2x + 4y ≥ 16
x + 2y ≥ 8.
Hence the system is:
y ≥ 2.3x + 2y ≥ 10.x + 2y ≥ 8.Each ounce of fruit contains 40 calories, and each ounce of nuts contains 50 calories, hence the calories function is:
Calories function = 40x + 50y.
Possible solutions to the system, containing only integers, as units is an integer amount, and their calorie consumption are:
x = 4, y = 2: calories: 40(4) + 50(2) = 260.x = 2, y = 3: calories: 40(2) + 50(3) = 230.x = 1, y = 4: calories: 40 + 50(4) = 240.Hence the quantities with the least calories are: 2 ounces of fruit and 3 ounces of nuts, with a calorie load of 230 calories.

The slope of the line passing through the points (4, -5), (-4, -5) is m = 0.
What do we mean by a slope?The slope of a line can be used to gauge how steep it is.Mathematically, the slope is calculated as "rise over run" (change in y divided by change in x).Every time the equation of a line is written as y = mx + b, the slope-intercept form of the equation is used.The slope of the line is shown by M.B is the value of b at the location of the y-intercept (0, b).For instance, y = 3x - 7 has a slope and y-intercept of 3 and 0, respectively.So, the slope of (4, -5) (-4, -5):
The slope formula: m = y₂ - y₁/x₂ - x₁Now, substitute the values in the formula and find the slope as follows:
m = y₂ - y₁/x₂ - x₁m = (-5) - (-5)/(-4) - 4m = -5 + 5/-4 - 4m = 0/-8m = 0Therefore, the slope of the line passing through the points (4, -5), (-4, -5) is

The length of a rectangle is 3 more than the width. Find the length of the rectangle if the perimeter is 98 in.A.47.5 inB.24.5 inC.26 in.D.23 in.
Answers
Answer
Length of the rectangle = 26 inches
Explanation
Let the length of a rectangle be L
Let the width of the rectangle be W
The length of the rectangle is 3 more than the width.
L = W + 3
But we are provided with the perimeter of the rectangle.
The perimeter of a figure is the sum of the dimensions of its exterior.
For a rectangle,
Perimeter = 2 (L + W)
For this question,
Perimeter = 98 inches
L = W + 3
W = ?
Perimeter = 2 (L + W)
98 = 2 (W + 3 + W)
98 = 2 (2W + 3)
98 = 4W + 6
4W + 6 = 98
4W = 98 - 6
4W = 92
Divide both sides by 4
(4W/4) = (92/4)
W = 23 inches
L = W + 3 = 23 + 3 = 26 inches

Use intercepts to graph the line described by the equation.4y =5x +20
Answers
We have to graph the equation 4y=5x+20 using the intercepts.
First we are going to find the y-intercept of the line, to do this we have to remember that the line intercepts the y-axis when x=0. Plugging this value of x in the equation we have
[tex]\begin{gathered} 4y=5(0)+20 \\ 4y=20 \\ y=\frac{20}{4} \\ y=5 \end{gathered}[/tex]Hence the y-intercept is 5. This represents the point (0,5).
Now we draw this point on the graph:
Now we have to find the x-intercept of the line, this happens when y=0. Plugging this value of y in the equation we have that
[tex]\begin{gathered} 4(0)=5x+20 \\ 0=5x+20 \\ 5x=-20 \\ x=-\frac{20}{5} \\ x=-4 \end{gathered}[/tex]Then, the x-intercept is -4. This represents the point (-4,0).
Drawing this point on the graph we have.
Now we only connect the points with a straight line:
That's the graph of the line that we find with the intercepts.

What is temperature range?Temperature range is defined as the difference between the degree of hotness and coldness of two different places.
The average daily high temperature of the month = 90°F
The average daily low temperature of the month = 69°F
The temperature difference between the two ranges = 90 -69 = 21°F
When both temperature are compared = 90+69/2 = 159/2 = 79.5°F
The percent increase of daily low temperature;

Marques works in a department store selling clothing. He makes a guaranteed salary of $200 per week, but is paid a commission on top of his base salary equal to 10% of his total sales for the week. How much would Marques make in a week in which he made $750 in sales? How much would Marques make in a week if he made x dollars in sales?
Answers
Base salary = $200 per week
Commission = 10% of total sales for that week
In a certain week, he makes sale of = $750
So, commission for that week = 10% of $750 = 10/100 x $750 = $75
In that particular week, Marques earned = base salary + commission = $200 + $75 = $275
For a week, in which he makes x dollars in sales,
Commission = 10% of x = 10/100 x (x) = $x/10
Total earning for that week = base salary + commission = $200 + $x/10
What are Commissions?The payment for goods or services sold in the form of commissions is a type of variable pay. Salesperson motivation and reward frequently involve commissions. Incentives like commissions might be used to promote particular sales techniques. When offering substantial reductions, for instance, commissions might be cut. Alternatively, commissions could go up when a company sells a certain product it wishes to advertise. A sales incentive program's framework, which may comprise one or more commission programs, governs how commissions are normally administered.The principal-agent problem is often solved by businesses by calculating payments as a proportion of revenue in an effort to better align employee interests with those of the business.Creating incentives that take account of an agent's performance is one of the most popular ways to try and balance principal and agent interests.
