In calculation, the precise bisector is a line section that separates a point into two equivalent points and parts.
The measure of P Q R is equal to the sum of ∠PQT and ∠TQR if line segment QT is the angular bisector of an angle ∠PQR.
∠PQR is equal to ∠PQT + ∠TQR.
There are three angular bisectors that can be made in a triangle, and all of them meet at the incenter of the triangle because line Q T is the angular bisector of P Q R. As a result, P Q T = T Q R.
BD divides ABC into two angles, ABD and DBC, given that line.
Additionally, given that DBC = 20 x + 16
ABD = 12 x + 24
Therefore, A B C = ABD + DBC (1) and ABD = DBC (2) respectively.
According to the second equation, 12 x + 24 = 20 x + 16 24 16 = 20 x 12 x 8 x = 8 x = 8 8 = 1
As a result, A B D = 12 (1) + 24; A B D = 36;
D B C = 20 (1) + 16; A B C = 36.
As a result of the equation (1), A B C = A B D + D B C;
A B C = 36; A B C = 72.
Therefore, ∠ABC measure 72.

A person invests 10000 dollars in a bank. The bank pays 6.5% interest compounded
annually. To the nearest tenth of a year, how long must the person leave the money
in the bank until it reaches 29500 dollars?
Answer: 3000 years
Step-by-step explanation:
Let y be the number of money and x be the number of years
So we have the equation
y= 6.5x + 10000
Now we put 29500 in the y
29500 = 6.5x + 10000
Subtracted 10000 from both sides
19500 = 6.5x
Divided both sides by 6.5
x = 3000 years
How do you measure the length of a line segment using a ruler or a compass? Explain the steps and show your work.
To measure the length of a line segment AB, place the zero marking of the ruler along the beginning of the line and measure its length.
A line segment has two definite endpoints in a line, and the line segment is fixed, which is the distance between two fixed points. The length can be measured by metric units such as centimeters, and millimeters.
A line segment with two endpoints A and B and is denoted by the bar symbol (—).
Using Ruler and Compass:
There are some markings on the ruler beginning from zero as shown in the figure. these markings divide the ruler into equal parts.
Each part is equal to a length of 1 cm and these units are measured in centimeters and are further subdivided into 10 parts and each sub-part is equivalent to 1 millimeter.
To measure a line segment AB, place the zero marking of the ruler along the beginning of the line and measure its length accordingly.
ln the figure, the length of line segment AB is 8 cm.

what can we conclude about the endogeneity of an explanatory variable if the ols and 2sls estimates are significantly different? assume that the instrument used was exogenous.
Note that assuming that the instrument used was exogenous, one can conclude about the endogeneity of an explanatory variable if the OLS and 2SLS estimates are significantly different: "The explanatory variable is endogenous and therefore 2SLS should be considered." (Option C)
What is 2SLS?Two-stage least squares (2SLS) regression analysis is a statistical approach used in structural equation analysis. The OLS approach has been extended using this methodology. It is employed when the error terms of the dependent variable are associated with the independent variables.
The ordinary least squares (OLS) approach is a linear regression methodology used to estimate a model's unknown parameters. The strategy is based on reducing the sum of squared residuals between the expected and actual values.
2SLS is utilized as an alternate strategy when we encounter endogeneity Problems in OLS. Endogeneity arises when the explanatory variable correlates with the error word. Then we utilize 2SLS, which employs an instrumental variable. The outcome will be different because if there is endogeneity in the model, OLS will produce biased results.

Leo argues that the measure of an exterior angle of a triangle is
equal to the sum of the measures of the two remote interior angles of
the triangle. He uses the diagram shown in his argument.
Xº
Leo writes the steps listed.
Step 1.r+x=180, since the sum of the measures of supplementary
angles is 180°
Step 2. p+q+r=180, since the sum of the measures of the angles
of any triangle is 180°
Which equations follow from step 1 and step 2 that Leo could use to
complete his argument?
r+x=p+q+r
r+x-r=p+q+r-r
x=p+q
p+q+r=180
bp+q+r-r=180-r
p+q=180-r
x+r=p+q+r
x+r-r=p+q+r+r
x=p+q+2r
(r+x) + (p+q+r)=180+180
2r+x+p+q=360
Answer:
Step-by-step explanation: It looks like Leo is trying to prove that the measure of an exterior angle of a triangle is equal to the sum of the measures of the two remote interior angles of the triangle. From the equations given, it seems that Leo is using the fact that the sum of the measures of supplementary angles is 180 degrees, and the sum of the measures of the angles of any triangle is 180 degrees, to try to prove his statement. Some equations that Leo could use to complete his argument might include:
x = p + q, which follows from the equation r + x = 180 and the substitution of p + q + r = 180
p + q = 180 - r, which follows from the equation p + q + r = 180 and the substitution of r + x = 180
x = p + q + 2r, which follows from the equation x + r = p + q + r and the substitution of r + x = 180
It's not clear from the information given whether these equations are sufficient to prove Leo's statement, as we don't have any information about the values of p, q, r, or x. However, these equations might be a good starting point for Leo to continue his argument.

If EDC measures 117° then the measure of E'D'C' is___ If AB measures 1.8 inches and A'B' measures 4.5 inches, then the scale factor r is____
Name one segment from polygon ABCDEF and one segment from polygon A'B'C'D'E'F' that are parallel.
Step-by-step explanation:
in a dilation all the angles stay the same. only the lengths of lines (like sides or heights) change - and all with the same scale factor (which makes the original and the dilated result similar objects).
angle EDC = 117°.
therefore angle E'D'C' = 117°.
AB = 1.8 in
A'B' = 4.5 in
the scale factor r is
r = 4.5 / 1.8 = 2.5
every segment of A'B'C'D'E'F' is parallel to its original counterpart in ABCDEF.

Please refer to the photo taken.
Answer:
-(√2 +√6)/4
Step-by-step explanation:
You want the exact value of sin(17π/12).
Sine of sumThe sine can be written as ...
sin(17π/12) = sin(π +5/12π)
= -sin(5/12π) = -sin(2/12π +3/12π)
= -sin(π/6 +π/4)
= -(sin(π/6)cos(π/4) +cos(π/6)sin(π/4))
= -((1/2)(√2/2) +(√3/2)(√2/2))
= -(√2 +√6)/4
The sine of 17π/12 is -(√2+√6)/4.

the diameter of a circle is 16. by what number must the radius be decreased in order to decrease the area of the circle by $48\pi$?
To decrease the area of the circle by $48\pi$, we need to decrease the radius by a factor of $\sqrt{48\pi}$.
Since the original radius of the circle was 8, the radius must be decreased to
$\frac{8}{\sqrt{48\pi}} = \frac{8}{\sqrt{48}\sqrt{\pi}} = \frac{8}{\sqrt{48}} \approx \frac{8}{6.9282} \approx 1.1547$.Therefore, to decrease the area of the circle by $48\pi$, the radius must be decreased by a factor of about 1.1547.
This means that the radius must be decreased by a number that is about 1.1547 times smaller than the original radius of 8, or by about $8 \times (1 - 1.1547) = -0.6158$.

Comparing both given functions, we can state that: B. Function 1 has the greater rate of change; the slope is 2.
What is the Rate of Change/Slope of a Function?Another name for the rate of change of a function is the slope. It is calculated using the formula:
Slope / rate of change = change in y / change in x.
If the equation of a linear function is given in slope-intercept form as y = mx + b, the rate of change or the slope is represented by "m".
Given the first function as an equation, y = 2x - 6, the slope of this function is represented as 2. This means, the rate of change is m = 2.
To find the rate of change of function 2, use two points from the table, (1, -4) and (2, -5):
Rate of change / slope (m) = (-5 - (-4)) / (2 - 1) = -1/1
m = -1.
The slope value of 2 is greater than the slope value of -1, therefore, we can conclude that: B. Function 1 has the greater rate of change; the slope is 2.
