According to the exterior angle theorem, an external angle's measure is equal to the sum of its remote interior angle's two measurements. The opposite interior angles are another name for the remote interior angles. Where can I determine a triangle's outer angle? In a triangle, how can I determine the interior and outside angles?
Take the total of two interior angles of a triangle that are known and deduct it from 180 to find the internal angle of the triangle.
Simple addition of the triangle's two opposite internal angles will yield the triangle's external angle. 180° minus the inside angle equals each exterior angle. Using this formula requires the knowledge of the corresponding internal angle. Exterior angle = Total.

how do you find the equation of line passing through (0,0) and (4,4)
Answers
Answer:
y = mx
Step-by-step explanation:
It depends on what form of the line that you want. Usually the slope intercept form is wanted.
y = mx + b We need to have the m (slope) and the b (the y-intercept)
The slope is the change in y over the change in x.
Ordered pairs are in the form (x,y)
(0,0) and (4,4) Have x's of 4 and 0, and y's of 4 and 0. We subtract these to find the changes in y and x.
[tex]\frac{4-0}{4-0}[/tex] This is [tex]\frac{4}{4}[/tex] which is the same as 1. The slope (m) is 1.
Now we need to find the y -intercept. The y intercept is the point where x is 0 (0,b). They give us this point (0,0,) So the y -intercept is zero.
y = 1m + 0
or y =mx

Answers
The thing that is wrong with the bookkeeper’s entry assuming Karlin uses the allowance method is that the company uses allowance method and thus the write-off entry would not be to bad debt account.
How yo illustrate the information?
It should be noted that because the business is using the allowance approach in this instance, the write-off entry would not be to the account for bad debts. To write off an account, a debit must be made to a separate account that is kept as an allowance for dubious accounts.
Since the receivables would not be collected, the accounts receivable account would be credited. In this case,the write off isn't appropriately illustrated in the account.

First angle:
Second angle:
Third angle:
Answers
Answer:
First, let one angle be a variable (eg: x) so that you can form expressions and solve.
Let the first angle be x°.
Then we can form expressions for the second and third angles using the information given.
First angle = x°
Second angle = (x + 10)°
Third angle = (3x)°
Since sum of angles in a triangle is 180°, we can form an equation.
x + (x + 10) + 3x = 180
Simplify and solve for x.
5x + 10 = 180
5x = 170
x = 34
Substitute x into the expressions to find the angles.
First angle = 34°
Second angle = 34 + 10
= 44°
Third angle = 3(34)
= 102°

Volunteers are preparing identical backpacks for refugees. There are 32 maps and 24 dictionaries to use for the backpacks. What is the greatest number of backpacks they can prepare using all of the maps and dictionaries?
Answers
Considering the definition of greatest common divisor, the greatest number of backpacks volunteers can prepare using all of the maps and dictionaries is 8.
Definition of greatest common divisorConsidering that a divisor can be formally defined as that number that is contained in another exactly n times, the greatest common divisor is the largest number by which two or more numbers can be divided. That is, the greatest common factor is the highest number by which a set of numbers can be divided, resulting in a whole number.
To calculate the greatest common factor, the following steps must be followed:
Decompose each number into prime factors. [The prime factors of an integer are the exact divisors of that integer, that is, they have only two divisors: one and themselves]Then point out the common factors.In each of the common factors, choose the factor with the smallest exponent.Multiply the chosen factors.Greatest number of backpacks preparedIn this case, you must calculate the greatest common factor as follows:
Decomposition of 32: 2⁵Decomposition of 24: 2³×32 is the factor common to both numbers, with 3 being the smallest exponent found. Then the greatest common divisor is calculated as:
Greatest common divisor= 2³
Greatest common divisor= 8
This means that they can prepare 8 backpacks.

Present age of father is 48 years and that of son is 23 years.
Let the age of father be x years
And the son's age be y years
According to the question,
x - y = 25 -----------1
15 Years ago, x= 6( y - 15 )
x= 6y - 90 -------------2
Substituting value of x from equation 2 in equation 1, we get
6y - 90 - y = 25
5y -90 = 25
5y = 25+90
5y= 115
y= 23
Therefore son's age is 23 years and from equation 1 we get x= 25+y = 25+23 = 48 years. So father's age is 48 years.

What are the properties of equality?Properties of equality includes; addition, subtraction, transitive, reflexive, and symmetric properties of equality
Transitive PropertyThe transitive property of equality can be stated as follows; If two variables are each equal to a third variable, then the two variables are equal to each other.
Therefore; a = b and b = c then a = c represents the transitive property
Division property of equalityThe division property states that both sides of an equation remain equal, following a division of both sides by the same non zero number
Therefore;
If a = b then a ÷ c = b ÷ c; represents the division property of equality
Reflexive propertyThe reflexive property of equality states that a measure or number is always equal to itself
Therefore;
a = a represents the reflexive property
Substitution PropertySubstitution property indicates that if two variables are equal, then one can replace the other in an equation and the results will remain the same
Therefore;
If x + a = b and x = c then c + a = b; represents the substitution property
Addition and Subtraction Property of EqualityThe statement of the addition (and subtraction) property of equality is that both sides of an equation remain equal following the addition or subtraction of the same amount from both sides the same
Therefore;
If a = b then a + c = b + c; represents the addition property of equality
If a = b then a - c = b - c; represents the subtraction property of equality
Multiplication Property of EqualityThis states that both sides of an equation remain equal following the multiplication of both sides by the same value
Symmetric PropertyThe symmetric property states that two sides of an equation remain equal when their relative positions are interchanged
Distributive PropertyThis states that two sides of an equation remain equal following a distribution with multiplication over addition or subtraction.

Answers
The length and width of the rectangle with a perimeter of 378ft are 168ft and 21ft respectively.
What is the length and the width of the rectangle?The formula used in calculating the perimeter of a rectangle is expressed as;
P = 2( l + w )
Where l is length and w is width.
Given the data in the question;
Let 'x' represent the width of the rectangle.
Width of the rectangle w = xLength of the rectangle l = 8xPerimeter P = 378ftPlug the given values into perimeter formula and solve for x .
P = 2( l + w )
378 = 2( 8x + x )
378 = 2( 9x )
378 = 18x
18x = 378
x = 378/18
x = 21
Now, we find the length and width of the rectangle.
Width of the rectangle w = x = 21ft
Length of the rectangle l = 8x = 8( 21 ) = 168ft
Therefore, the width of the rectangle is 21ft while its length is 168ft.

Answers
The x and y solution of the system is x = -3 and y = -6
How to determine the solution to the system?A system of linear equations is a collection of at least two linear equations.
In this case, the system of equations is given as
6 = −4x + y
− 5x − y = 21
Make -y the subject in the second equation, by adding 5x to both sides of the equation
5x − 5x − y = 21 + 5x
This gives
−y = 21 + 5x
Substitute −y = 21 + 5x in 6 = −4x + y
6 = −4x - 21 - 5x
Evaluate the like terms
5x + 4x = -6 - 21
This gives
9x = -27
So, we have
x = -3
Substitute x = -3 in −y = 21 + 5x
−y = 21 + 5 * -3
Evaluate
−y = 6
So, we have
y = -6
Hence, the solution for the system of linear equations 6 = −4x + y and − 5x − y = 21 is x = -3 and y = -6
