Solve for m.D:
D (9x-44)
X =
(6x+7)
Answer:
m∠D = 109
Step-by-step explanation:
This is a parallelogram.
In parallelograms, the opposite interior angles are congruent, so we can write the following equation to find, first value x the measure of m∠D:
9x - 44 = 6x + 7
Transfer like terms to the same side of the equation.9x - 6x = 7 + 44
Add/subtract.3x = 51
Divide both sides by 3x = 17
Now we can calculate measure of m∠D:
m∠D = 9x - 44
Rewrite equation using the value we found for x.9×17 + 44 = 109

Why do parallel lines require the undefined terms of line and plane?.
Parallel lines require the terms line and plane because line and plane that are parallel cannot cross each other. Thus, they will never create a point of intersection. The characteristics of that parallel lines consist of lines and planes.
The characteristics of parallel lines are;
The shortest distance between parallel lines is the same at all points along the lines.
The lines are on the same plane.
As the plane is prolonged indefinitely, the lines do not intersect.
The characteristic of these geometric figures that create the different requirements would be how these undefined terms are situated. In the case of parallel lines, these are lines that would not intersect no matter how long the line is extended or whether it goes infinitely; thus, the lines lie on the same plane.

Answer:
0.8 meters is the width.
Step-by-step explanation:
Answer: 0.8
Step-by-step explanation: All you have to do is set the equation up so you're looking at the length being twice the width (which in equation form would be l=2w) then you say there is two lengths, so you have 4w. Then you add the original width to the lengths (2w) so you have 6w= 0.8

In Euclidean geometry, any three factors, while non-collinear, decide a completely unique triangle and simultaneously, a unique plane (i.e. a -dimensional Euclidean space). In different words, there's best one plane that consists of that triangle, and every triangle is contained in some plane.

How do you find the mean median and mode in class 9?.
To find the mean, median and mode add up the values and divide, the value of set in middle of the list and identify the most number of times a number is repeated.
The sum of all observations divided by the total number of observations yields the arithmetic mean of a set of data. For illustration, a cricketer's five ODI scores are as follows: 12, 34, 45, 50, 24. We compute the arithmetic mean of the data using the mean formula in order to get his typical score in a game:
Mean = Sum of all observations/Number of observations
Mean = (12 + 34 + 45 + 50 + 24)/5
Mean = 165/5 = 33
The median of the data is the value of the middle observation after the data have been arranged in either ascending or descending order.
Take these numbers as an example: 4, 4, 6, 3, 2. Let's organize these numbers ascending: 2, 3, 4, 4, 6.
Median = (n + 1)/2th observation

Use the graph to write a linear function that relates y to x
The linear function of the graph is written as: y = 4/3x + 2.
How to Write a Linear Function that Relates y to x of a Graph?The most common form of a linear function is y = mx + b, where m is the slope of the line and b is the y-intercept.
To write a linear function in this form, you will need to find the slope and y-intercept of the line.
The slope is the ratio of the change in y to the change in x, and the y-intercept is the point at which the line crosses the y-axis. Once you have these two values, you can substitute them into the equation and write the linear function.
Using the given graph:
Slope (m) = rise/run = 8/6
Slope (m) = 4/3
The y-intercept (b) = 2.

Answer: 126 mm^2 - C
Step-by-step explanation: Hello! The formula for area of a triangle is 1/2(b)(h). b = base and h = height. You would multiply the base and height by 1/2 because a triangle is 1/2 the size of a square. The formula for the area of a square is (b)(h), and you would have to multiply (b)(h) to find the area of a triangle with the same base and height. The base of this triangle is 28 mm, and the height of this triangle is 9 mm. Substitute 28 mm in for the base, and 9 mm in for the height. (28)x(9) = 252. Now you have to multiply 252 x 1/2. 252 x 1/2 = 126. The answer is C, 126.

How to solve triangles?.
There are several methods to solve a triangle such as SSS, SAS, ASA, and HL, using the Pythagorean theorem, the Law of Sines, and the Law of Cosines.
SSS (Side-Side-Side) Congruence: If the lengths of all three sides of one triangle are equal to the lengths of all three sides of another triangle, the two triangles are congruent.SAS (Side-Angle-Side) Congruence: If two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, the two triangles are congruent.ASA (Angle-Side-Angle) Congruence: If two angles and the included side of one triangle are equal to two angles and the included side of another triangle, the two triangles are congruent.HL (Hypotenuse-Leg) Congruence: If the hypotenuse and one leg of one right triangle are equal to the hypotenuse and one leg of another right triangle, the two triangles are congruent.Using the Pythagorean theorem: In a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs.Law of Sines: states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all three sides of the triangle.Law of Cosines: states that the square of the length of the hypotenuse of a triangle is equal to the sum of the squares of the lengths of the legs, minus twice the product of the lengths of the legs and the cosine of the angle between them.To learn more about the triangle, visit:
