Angles A and Care supplementary. Find the measure of angle C.
There is a picture
Answers
Answer:
106 degrees
Step-by-step explanation:
180 -74 = 106
The second option is correct i.e. [tex]m[/tex]∠C = 106 degrees.
What are supplementary angles?Two angles are said to be supplementary angles when they add up to 180 degrees.
Two angles are supplementary, if
a). one of its angle is an acute angle and another angle is an obtuse angle.
b). both of the angles are right angles.
This means that if A and B are the two angles then
[tex]m[/tex]∠A+[tex]m[/tex]∠B = 180 degrees
According to the given question we have
angles A and C are supplementary
and, [tex]m[/tex]∠A = 74 degrees
therefore,
the measure of angle C is calculated as
[tex]m[/tex]∠A + [tex]m[/tex]∠C = 180 degrees (sum of the supplementary angles)
74 + [tex]m[/tex]∠C = 180 degrees ( [tex]m[/tex]∠A = 74 )
[tex]m[/tex]∠C = (180 - 74)degrees ( subtracting 74 degrees both the sides)
[tex]m[/tex]∠C = 106 degrees
Hence, second option is correct i.e. [tex]m[/tex]∠C = 106 degrees.

Great freight a local shipping company charges .40 per pound for shipping if your shipping 20 pounds what would the cost be
Answers
Answer:
$8.00
Step-by-step explanation:
For every pound shipped, $0.40 is charged. This can be represented by the mathematical equation: y=0.4x, where x is the pounds to ship and y is the total cost. If we plug in 20 as x to find what the total cost would be, we would have the equation, y=0.4*20, and y would equal 8, meaning that the total cost is $8.00.

An undefined term used in geometry?Three undefined concepts, or terms that don't need to be specified separately even though they are utilized to construct more intricate parts, are present in this case of Euclidean geometry.The three terms in geometry that aren't specified are:1. Point2.Line\s3. PlaneIn cartesian space, for example, a point cannot be defined specifically but can be utilized to define any triangle, line segment, or cube among other 2D or 3D objects. Similar to this, a line is nothing more than another arrangement of points that is used to define more intricate objects like a wire. While a plane is simply a group of lines arranged in a specific location and orientation, similar to a piece of land.

How to solve a linear equation?A linear equation can be solved by equating the LHS and RHS of the equation following some basic rules such as by adding or subtracting the same numbers on both sides and similarly, doing division and multiplication with the same numbers.
Suppose the age of man be x.
Then, age of his daughter is x - 32.
As per the question the following equation can be formed for the product of ages as ,
x(x - 32) = 320
⇒ x² - 32x - 320 = 0
⇒ x = 40, -8
Since, age of a person cannot be a negative value, it is taken as positive.
Thus, the age of daughter is 40 - 32 = 8
Hence, the age of the man and his daughter is obtained as 40 and 8 years respectively.

What is Regression line?An estimate of the line that depicts the actual, but unidentified, linear relationship between the two variables is called a regression line. When the value of the explanatory variable is known, the regression line's equation is used to predict (or estimate) the value of the response variable.
Given:
Using the regression model
In II nd week the calories is 2950 and weight 250.
and, Vth week the calories is 7400 and weight 216.
let Exercise be x and the weight is y then
= (216 - 250)/ (7400- 2950)
= -9/ 4450
So, at the start of week john weight
y= -9/ 4500 x + 230
Now, At the end of 8 week John weighs
= -9/4500 (6100) + 230
= 217.7

verify that 1,-1,-3 are the zeroes of the cubic polynomial x3+3x2-x-3 and check the relationship between zeroes and the coefficient
Answers
Answer: yea its 123445
Step-by-step explanation:
1,-1,-3 are the zeroes and the relationship between zeroes and the coefficient is verified.
What is a Polynomial?Polynomial, a mathematical expression made comprised of numbers and variables arranged in specific patterns.
As per the given data:
We are given the equation of a cubic polynomial x³ + 3x² - x - 3.
The zeroes of the given cubic polynomial are also given.
We have to verify that the zeroes of the cubic polynomial are correct, and they satisfy the relationship between zeroes and the coefficient.
For a polynomial p(x) is p(a) = 0 then a is a zero of p(x).
Checking the given zeroes similarly:
For 1:
1³ + 3(1)² - 1 - 3 = 0
1 + 3 - 1 - 3 = 0
0 = 0
1 is a zero
For -1:
(-1)³ + 3(-1)² - (-1) - 3 = 0
-1 + 3 + 1 - 3 = 0
0 = 0
-1 is a zero
For -3:
(-3)³ + 3(-3)² - (-3) - 3 = 0
-27 + 27 + 3 - 3 = 0
0 = 0
-3 is a zero
For ax³ + bx² + cx + d = 0, the sum of all the roots should be equal to
= (-b)/a
Similarly, for x³ + 3x² - x - 3:
1 + (-1) + (-3) = (-3)/1
1 - 1 - 3 = -3
-3 = -3
1,-1,-3 are the zeroes and the relationship between zeroes and the coefficient is verified.
Hence, 1,-1,-3 are the zeroes and the relationship between zeroes and the coefficient is verified.

Answer:
m<2 = 120
Step-by-step explanation:
When two lines are parallel and are intersected by a transversal, same side exterior angles are supplementary, meaning that their angle measures add up to 180 degrees.
Using this, one can form the equation;
m<8 + m<2 = 180
Substitute,
60 + m<2 = 180
Inverse operations,
60 + m<2 = 180
-60 -60
m<2 = 120
Answer:
Step-by-step explanation:
Solution
<8 = 60 degrees.
<6 is <8s supplement
<6 + <6 = 180
60 + <6 = 180
<6 = 180 - 60
<6 = 120
<2 and <6 are corresponding angles and are therefore equal.
<2 = 120
