After solving the equation we know ABCD is a parallelogram.
What is parallelogram?
A parallelogram is a two-dimensional shape with four straight sides. All of the sides are equal in length and the opposite sides are parallel. Additionally, opposite angles are also equal. The shape is called a parallelogram because parallel lines are present on either side. Parallelograms can come in many different forms, such as rectangles and rhombuses. The properties of a parallelogram include the fact that the diagonal line that divides the parallelogram into two halves bisects the angles. Additionally, the cross product of the two diagonals is equal to the area of the parallelogram. Parallelograms are used in a variety of areas, including architecture, engineering, and mathematics. Depending on the application, parallelograms can be used to construct a variety of shapes, such as circles and ellipses.
Given: A (2,5), B (7,6), C (6,2), D (1,1)
AB ⇒ A (2,5), B (7,6) = [tex]\sqrt{(x_{2}-x_{1} ) ^{2} +(y_{2}-y_{1} )^{2} }[/tex]
⇒ [tex]\sqrt{(-5+1)^{2}+(-6-2)^{2} }[/tex]
⇒ [tex]\sqrt{(-4)^2+(-8)^{2} }[/tex]
⇒ [tex]\sqrt{16+64} =\sqrt{80}[/tex]
CD ⇒ C (6,2), D (1,1) = [tex]\sqrt{(x_{2}-x_{1} ) ^{2} +(y_{2}-y_{1} )^{2} }[/tex]

⇒ [tex]\sqrt{(4)^2+(8)^{2} }[/tex]
⇒ [tex]\sqrt{16+64} =\sqrt{80}[/tex]
BC = B (7,6), C (6,2) ⇒ [tex]\sqrt{(x_{2}-x_{1} ) ^{2} +(y_{2}-y_{1} )^{2} }[/tex]
⇒ [tex]\sqrt{(3+5)^{2}+(-2+6)^{2} }[/tex]
⇒ [tex]\sqrt{(8)^{2} +(4)^{2} }[/tex]
⇒ [tex]\sqrt{16+64} =\sqrt{80}[/tex]
AD ⇒ A (2,5), D (1,1) = [tex]\sqrt{(x_{2}-x_{1} ) ^{2} +(y_{2}-y_{1} )^{2} }[/tex]
⇒ [tex]\sqrt{(7+1)^{2}+(6-2)^{2} }[/tex]
⇒ [tex]\sqrt{(8)^{2} +(4)^{2} }[/tex]
⇒ [tex]\sqrt{16+64} =\sqrt{80}[/tex]
As, AB = CD = BC = AD all sides are equal.
Hence proved, ABCD is a parallelogram.

Additionally, 140 is the sum of all of them,
thus,
2x + 3y + y < 140
2x + 4y < 140
x + 2y < 70
x + 2 × 7x/3 < 70
3x + 14x < 210

What are similar triangles?
Similar triangles are triangles that have constant form, however their sizes could vary. All equal triangles, squares of any facet lengths area unit samples of similar objects. In alternative words, if 2 triangles area unit similar, then their corresponding angles area unit congruent and corresponding sides area unit in equal proportion.
Main body:
according to question :
height of wooden pole = 144 inches = 12 ft
(as 12 inches = 1 ft
therefore 144 inches = 12 ft)
distance between telephone pole and wooden pole = 45 ft
distance between pole and stake = 57.5 ft
distance between wooden pole and stake = 57.5 - 45 = 12.5 ft
we need to find height of telephone pole =?
as ΔABE are similar to ΔCDE , so
AB/BE = CD/CE
AB/57.5 = 12/12.5
AB = 12*57.5/12.5
AB = 55.2 ft

the hour property of the datetime structure stores the hour as an integer between 1 and 24. question 47 options: true false
False. The hour property of the datetime structure stores the hour as an integer between 0 and 23.
To support varied needs, three different property types are available:
1. Date — A day of the Gregorian calendar, without reference to a time zone or locale. The unit is a whole day, such as July 23, 2006.
2. Time of Day — A time of day, without reference to a time zone or locale. The unit is seconds, such as 15 seconds after 1:25 P.M.
3. Date Time — A date and time, stored internally to the millisecond if available, in a known time zone. For example 15.452 seconds after midnight on July 23, 2006 in London, U. K.
When presented with a DateTime value, a corresponding date and a time-of-day (in a specified time zone) can be determined.
However, the converse is not usually true: when starting with a Date and a TimeofDay value, multiple differing but "correct" DateTime values can be constructed, depending on assumptions about time zone, Daylight Savings Time, and other considerations. For example, when the date is January 1 in London, it can be December 31 in New York.
