Some figures are given in the question.
We have to find out which of the given figures have 180 degree rotation symmetry.
What do you mean by rotational symmetry ?
Rotational symmetry is defined as the property a shape has when it looks the same after some no. of rotations.
As per the question ;
We have to check which of given figures have rotational symmetry.
We know that ;
For a shape to have a rotational symmetry, the following must be true ;
The shape must have an even number of sides i.e., 4 , 6 , etc.The shape must have equal and parallel opposite sides.If we check according to the above conditions ;
Figures (A) and (D) don't meet the conditions.
However, the above conditions are true for figures (B), (C) and (E).
This is because a rectangle , a square and a regular hexagon has equal & parallel opposite sides; and also even number of sides.
Thus , the figures having 180 degree rotation symmetry are figure B , figure C and figure E.

Answer:
B
Step-by-step explanation:
I think
Answer:
D. 41 and 43
Step-by-step explanation:
To find it, 54 times 6 plus the two numbers then divided by 8 has to equal 51. let a and b be the two numbers
[(54*6) + a + b]8 = 51
(324 + a + b)/8 = 51
324/8 + (a + b)/8 = 51
40.5 + (a + b)/8 = 51
(a + b)/8 = 10.5
a + b = 84
The mean if a and b are 42, what two numbers here have a mean of 42? 41 and 43, 41 + 43 = 84, 84/2 = 42
80% of a number is x.
What is 40% of that same number?
Answers
Answer:
Step-by-step explanation:
ntroduction. Percent, p%
'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100
80% = 80/100 = 80 ÷ 100 = 0.8
100% = 100/100 = 100 ÷ 100 = 1
Percentage of 80% of what number = 40?
80% of what number = 40 is equivalent to:
80% × ? = 40
80% × ? = 40
? =
40 ÷ 80% =
40 ÷ (80 ÷ 100) =
(100 × 40) ÷ 80 =
4,000 ÷ 80 =
50
40% is half of 80%. So the answer should be half of x.

There are two trianges each with a base of 3 and a height of 3, making each 4.5 units^2 and together, 9. Add the area of the triangles with the square to get 18.
Answer:
A = 18 cm²
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
where h is the perpendicular height and b₁, b₂ the parallel bases )
Here h= 3, b₁ = 3 and b₂ = 9 , then
A = [tex]\frac{1}{2}[/tex] × 3 × (3 + 9)
= 1.5 × 12
= 18 cm²
2.2 ≤ 2.25 true or false?
Answers
True,
2.2 is equal to 2.2 Imagine it like this.
22 < 225 correct right? Well look at this 22<22 is wrong it should be equal, so we added on a five to make it more greater!
Answer:
false
Step-by-step explanation:
≤ means greater than or equal to. 2.25 is greater than 2.2, there isn't a possibility that 2.2 is greater than 2.5 even if it was estimated 2.4 would be the greatest number, hence the use of ≤ is invalid.

•What is the value of X?
•What is the measure of angle C?
Also 50 points answer because I feel like it lol.
Answers
Answer:
solution given:
3(x+2)+35°+52°=180°[sum of interior angle of a traingle is 180°]
3(x+2)=180-87
x+2=93/3
x+2=31
x=31-2=29°
value of x=29°
again
<C=3(29°+2)=93°
the measure of angle C=93°
Answer:
x = 29
angle c = 93
Step-by-step explanation:
Angles in a triangle add up to equal 180
That being said we create an equation to solve for x
180 = 3(x+2) + 52 + 35
Now we solve for x using basic algebra
step 1 distribute the 3 to ( x and 2 )
3 * x = 3x
3 * 2 = 6
now we have 180 = 3x + 6 + 52 + 35
step 2 combine like terms
6 + 52 + 35 =93
now we have 180 = 93 + 3x
step 3 subtract 93 from each side
93 - 93 cancels out
180 - 93 = 87
now we have 87 = 3x
step 4 divide each side by 3
3x / 3 = x
87 / 3 = 29
we're left with x = 29
Now we want to find the measure of angle C
To do so we plug in 29 for "x" in 3 ( x + 2)
3 ( 29 + 2 )
29 + 2 = 31
3(31) = 93
Hence angle c = 93
