I think the angle of rotation for the following figure might be 120 degrees
The area of the park is 1640 square meters.
<h3>What is a quadrilateral?</h3>
A quadrilateral is a plane shape with four sides and four angles.
The above figure is made up of two quadrilateral; a square and a trapezium.
Analysis:
Area of park = area of square + area of trapezium
Area of park = 1/2(a + b)h + s x s
where a = length of smaller parallel side of the trapezium = 40m
b = length of the larger parallel side = 48m
h = height of trapezium = 35m
s = length of side of square = 10m
Area of park = 1/2(40 + 48)x35 + 10 x 10 = 1640 square meters
In conclusion, the area of the park is 1640 square meters

well, we can say that √2 and √7 are irrational numbers, they do not provide a value that can be written in a "ration" or fractional.
we can also say that √2 * √7 is √(14), which is also irrational.
However, how about √7 * √7, that's √7² or namely just 7, and that's a rational, so nope, not always.
2x³+18x²<span>-18x-162 =
2(</span>x³+9x²-9x-81)=
2(x²(x+9)-9(x+9))=
2(x²-9)(x+9)=
2(x+3)(x-3)(x+9)
Answer: k=3
Answer:
Rotational symmetry of 180° about the origin: Yes.
Rotational symmetry of 270° about the origin: No.
Explanation:
A figure is a rotationally symmetrical if it look the same after a given turn.
We have to analyze if the parallelogram has rotational symmetry of 180° or 270°. picture the figure rotating a given amount of degrees to see if it looks the same or not.
180 degree rotation:
We can see that the figure looks the same after a 180° rotation.
270 degree rotation:
We can see that the figure does not look the same after a 270° rotation.
So the answer will be:
Rotational symmetry of 180° about the origin: Yes.
Rotational symmetry of 270° about the origin: No.
