Does an uppercase h have point symmetry?

1 answer:

3 0

Yes. Point symmetry is effectively where an object is "the same upside down", or where every point has an identical counterpart the same distance from the point in the opposite direction. H can be flipped and remain symmetrical

Whats the value of x and what is the length of side UW

solmaris [256]

We will calculate this by using ratios and because these two triangles are similar, which is very important.

Explanation:

We see that the FG = 9 corresponds to the VU = 21. Therefore, FH = 18 corresponds to the UW = x.

9 : 21 = 18 : x

x = (21*18)/9

x = 378/9

x = 42.

The correct answer is B. 42.

Answer:

The answer is 5th angle = $\bold{42^\circ}$

Step-by-step explanation:

Given that pizza is divided into six unequal slices.

Largest slice has an angle of $90^\circ$ .

He eats the pizza from largest to smallest.

Let the difference in angles in each slice = $d^\circ$

1st angle = $90^\circ$

2nd angle = 90-d

3rd angle = 90-d-d = 90 - 2d

4th angle = 90-2d-d = 90 - 3d

5th angle = 90-3d-d = 90 - 4d

6th angle = 90-4d -d = 90 - 5d

We know that the sum of all the angles will be equal to $360^\circ$ (The sum of all the angles subtended at the center).

i.e.

$90+90-d+90-2d+90-3d+90-4d+90-5d=360\\\Rightarrow 540 - 15d = 360\\\Rightarrow 15d = 540 -360\\\Rightarrow 15d = 180\\\Rightarrow d = 12^\circ$

So, the angles will be:

1st angle = $90^\circ$

2nd angle = 90- 12 = 78

3rd angle = 78-12 = 66

4th angle = 66-12 = 54

5th angle = 54-12 = 42

6th angle = 42 -12 = 30

So, the answer is 5th angle = $\bold{42^\circ}$

297.3 = 2hundred, 9tens, 7 ones, and 3 tenths. Regroup 297.3 using 2 hundred, 9 tens, 5 ones, and ? tenths

Kipish [7]

297.3 to 295.?

to get to 297.3 from lets say 295.0 you need 2.3 more so a tenth is 0.1 so divide 2.3 by 0.1. you'll get 23 as the answer.

Find A ∩ B if A = {4, 7, 10, 13, 17} and B = {3, 5, 7, 9}.

castortr0y [4]

The answer is: <span>A ∩ B = 7

Given: </span><span>A = {4, 7, 10, 13, 17}
B = {3, 5, 7, 9}
</span>By the symbol, ∩, we mean which terms/objects are common in the the sets given to us.
Since only, 7 is the only number which is present in both set A and set B.
Therefore, A ∩ B = 7
