An irregular parallelogram rotates 360° about the midpoint of its diagonal. How many times does the image of the parallelogram c
oincide with its preimage during the rotation?
A.2
B.4
C.6
D.8

Answer:
The correct options is A.
Step-by-step explanation:
The each diagonal of an irregular parallelogram divides the parallelogram in two equal and congruent parts. The diagonal bisects each other.
It means, if a irregular parallelogram rotates 180° about the midpoint of its diagonal, then the image of the parallelogram coincide with its preimage during the rotation.
If a irregular parallelogram rotates 360° about the midpoint of its diagonal, then the image of the parallelogram coincide 2 times with its preimage during the rotation.
Therefore the correct option is A.

Slope:
y-intercept:
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:
Where "m" is the slope and "b" is the y-intercept.
The slope can be found with the following formula:
In this case you can say that:
Knowing this values you can substitute them into the formula and then evaluate, in order to find the slope. This is:
By definition, the line intersects the y-axis when the value of "x" is 0.
Notice in the table that when ,
Therefore, the y-intercept is:

Solution:
A triangle is a polygon with three sides and three angles. Types of triangles are scalene, acute, obtuse, isosceles, equilateral and right angled triangle.
A right angled triangle is a triangle with one angle equal to 90 degrees. The longest side of a right angled triangle is known as the hypotenuse. Trigonometric identities is used to show the relationship between the angles and sides of a right angled triangle, i.e.:
sinθ = opposite/hypotenuse; cosθ = adjacent / hypotenuse; tanθ = opposite / adjacent
From the image:
let the distance from jack to the base of the building be x, hence:
tan60 = x / 60
x = 60 * tan60 = 104 ft.
