Without knowing what the dropdown list shows for reasons, it's hard to pinpoint exactly what is expected here.
Angle ACD is congruent to angle BCD because they are corresponding angles between the congruent triangles ∆ACD and ∆BCD.
The triangle congruency is due to angle-angle-side (AAS) similarity:
• angles A and B are congruent - this is given
• angles CDB and CDA are congruent right angles - this is implied by the given detail that CD and AB are perpendicular
• the leg CD is common to both triangles, and CD is of course congruent to itself (reflexive property)
So angles ACD and BCD are congruent, which means they have the same measure, so by definition of angle bisector, CD bisects angle ACB.

It is an isosceles triangle.
A triangle with two equal sides is said to be isosceles. Also equal are the two angles that face the two equal sides. In other terms, an isosceles triangle is a triangle with two sides that are the same length.
There are mainly three types of triangles:
Equilateral triangle
A triangle with three equal-length sides is said to be equilateral, matching what might also be referred as as a "regular" triangle. Because all three sides of an isosceles triangle are equal, an equilateral triangle is a particular case of an isosceles triangle. There are three equal sides to an equilateral triangle.

What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.

Write each expression in simplest form. (-27x⁻⁹)¹/₃
The given expression can be written in its simplest form by using the rule of exponents.
There are three components to the given expression, there is a negative base term -27, there is a base term with negative exponent x^-9, and both base terms have a fractional exponent 1/3.
Solving the term with negative exponent, the rule dictates that a term with a negative exponent can be written as its reciprocal. As x^-n=1/x^n,
x^-9=1/x^9
Hence, the expression becomes (-27/x^9)^1/3
The fractional exponent is applied to both the base terms. As (x^n)^m=x^nm,
(-27/x^9)^¹/₃=(-27)^1/3/(x^9*1/3)
Solving the negative term, the rule dictates that when there is a negative term with an odd number power, the negative sign can be extracted from the expression.
Hence,
(-27)^1/3=-(27^1/3)
Further simplifying the term, we know that 3^3=27,
-(27^1/3)=-(3^3*1/3)
Multiplying the powers for the entire expression,
-(3^3*1/3)/(x^9*1/3)=-3^1/x^3=-3/x^3
The simplest form of the expression (-27x^-9)^¹/₃ is -3/x^3

find the product of two numbers whose sum is 11 and diffrence is 3
Answer:
The numbers are 4 and 7
Step-by-step explanation:
To start, we can set up two equations.
x + y = 11 and x - y = 3
We now need to solve for one of these variables in terms of the other. I am choosing to solve for x, but either way will work. I'm using the second equation and solving for x by adding y to each side, which gives me
x = 3 + y
Now that I have a value for x, I can plug this into my first equation
3 + y + y = 11
Combining like terms gives me
3 + 2y = 11
Subtracting 3 from both sides leaves
2y = 8
And dividing by 2 to solve for y gets
y = 4
We now know one number, and to solve for the other we can plug our y value into either equation
x + 4 = 11
Subtracting 4 from both sides yields the x value
x = 7
So the two numbers are 4 and 7

Find the value of y if M is the midpoint of LN. LM=9y-4 MN=6y+5 LN?
The value of y for which M is the mid-point of LN is equal to 3 and the numerical length of LN is 46 units.
What is Mid - point of a line?The mid - point of a line is the point which divides it into two equal parts of same length.
Given in the question is a line segment LN such that M is its mid - point. From the question, we can write -
LM = 9y - 4
MN = 6y + 5
According to the question, M is the midpoint of LN, therefore -
LM = MN
9y - 4 = 6y + 5
9y - 6y = 9
3y = 9
y = 3
So, the length of LN will be -
LN = LN + MN = 9 x 3 - 4 + 6 x 3 + 5 = 23 + 23 = 46 units
Therefore, the value of y is equal to 3 and the numerical length of LN is 46 units.

Which of the following equations have an infinite solution set?
The equation has infinite solutions is the last option:
6(x - 1) = 2*(3x - 3)
Which equation has an infinite solution set?Any equation in which we can remove the variable has infinite solutions (because it does not depend on the value of x) only if the equation is true.
Let's look at the fourth equation:
6(x - 1) = 2*(3x - 3)
If we expand both sides, we will get:
6x - 6 = 2*3x - 2*3
6x - 6 = 6x - 6
So we have the exact same thing in both sides, if we remove 6x - 6 in both sides we will get:

In geometry, a polygon may be a plane figure that is described by a finite number of straight line segments connected to form a closed polygonal chain (or polygonal circuit). The bounded plane region, the bounding circuit, or the 2 together, could also be called a polygon.The segments of a polygonal circuit are called its edges or sides. The points where two edges meet are the polygon's vertices (singular: vertex) or corners. the inside of a solid polygon is sometimes called its body. An n-gon may be a polygon with n sides; for example, a triangle may be a 3-gon.
A simple polygon is one which does not intersect itself. Mathematicians are often concerned only with the bounding polygonal chains of straightforward polygons and they often define a polygon accordingly. A polygonal boundary could also be allowed to cross over itself, creating star polygons and other self-intersecting polygons.

determine the rate of change and y-intercept
Answer:
The slope of the line is 12
(Sorry for the bad quality image)
Explanation:
To find the average rate of change, calculate the change in y over the change in x.
m = 12
Answer:
Rate of change = 12
y-intercept = (0, 20)
Step-by-step explanation:
Part 1) Rate of Change
The rate of change (or slope) is found using the formula [tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex].
To use this formula, we must take the coordinates of two of the given points in the table and substitute them. For simplicity, I'll take the points (1, 32) and (4, 68).
[tex]m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{68 - 32}{4 - 1} = \frac{36}3 = 12[/tex]
Therefore, the rate of change is 12.
Part 2) y-intercept
To find the y-intercept, we must find the value of the function where [tex]x = 0[/tex]. Since we have both the value of the function where [tex]x = 1[/tex] and we know that the rate of change is 12, we can simply subtract the rate of change from the y-value of the function at the point where [tex]x = 1[/tex].
The y-value of the function where [tex]x = 1[/tex] is 32, therefore, the y-value of the function at [tex]x = 0[/tex] is [tex]32 - 12 = 20[/tex]
The y-intercept is (0, 20).
