Answer:

P=6

Step-by-step explanation:

okay so the problem states that this pentagon has one line of symmetry.

if you know that AE=4x, AB=2x+1, and Bc=x+2, then you know that CD=x+2, and DE=2x+1.

since you know the perimeter is 18 cm, you can make an equation to find x:

4x+2(2x+1)+2(x+2)=18

-->4x+4x+2+2x+4=18

-->10x+6=18

-->10x=12

-->x=1.2

P would be 6

Answer:  It should be the third one

Step-by-step explanation:

A) In order to prove that these triangles are congruent by SAS, we need to have two sides of one triangle congruent to two sides of another triangle and an angle of one triangle (that’s included between the sides) is congruent to an angle of another triangle, the triangles are congruent.

We know that side OU is congruent to itself based on the reflexive property and we have a pair of right angles. However, we don’t know that sides MU is congruent to sides NU which would be our final step to prove these triangles are congruent by SAS.

So we are missing that sides MU and NU are congruent.

For part b, we have a pair of vertical angles which means they are congruent and <F and <S are congruent. For ASA, we need two angles and the included side of one triangle congruent to two angles and the included side of a second triangle.

We are not told that PQ and SQ have the same length, so this would be the information we would need to say these triangles are congruent by ASA.

Answer:

Step-by-step explanation:

x² = -64

   = -1 · 64

Using -1 = i²:

x² = 64 · i²

Using 64 = 8²:

x² = 8² · i²

   = (8·i)²

Taking the square root of both sides:

x = 8i

I think it 2 solution to the problem you can add or multiple

Similar figures are two or more given figures that have some common properties. The answers to the questions are;

14. m<WYZ = [tex]157^{o}[/tex]

15. m<ACB = [tex]87^{o}[/tex]

Two or more figures are said to be similar if they have some common properties. Note that similar figures may not be congruent.

Thus, the solutions to the questions can be determined as follows:

14. Comparing WYZ and VXYZ, we can deduce that:

<WYZ + <YVX = [tex]180^{o}[/tex] (sum of angles on a straight line))

So that;

(16x - 3) + (3x - 7) = [tex]180^{o}[/tex]

19x - 10 = [tex]180^{o}[/tex]

19x = [tex]190^{o}[/tex]

x = [tex]\frac{190}{19}[/tex]

  = [tex]10^{o}[/tex]

Then,

m<WYZ = (16x - 3) = (16(10) -3)

             = [tex]157^{o}[/tex]

The measure of angle WYZ is [tex]157^{o}[/tex].

15. (11x - 2) = (6x + 13)     (similarity property)

11x - 6x = 13 + 2

5x = 15

x = 3

So that;

m<ABC = (6x + 13) = (6(3) + 13)

             = [tex]31^{o}[/tex]

m<ABC = [tex]31^{o}[/tex]

But,

m<BAC + m<ABC + m<ACB = [tex]180^{o}[/tex]  (sum of angles in a triangle)

[tex]62^{o}[/tex] + [tex]31^{o}[/tex] + m<ACB = [tex]180^{o}[/tex]

m<ACB = [tex]180^{o}[/tex] - 93

             = [tex]87^{o}[/tex]

m<ACB = [tex]87^{o}[/tex]

The measure of angle ACB is [tex]87^{o}[/tex].

Answer:

3 hours 45 minutes

Step-by-step explanation:

270/2 1/2 = 108. This means they are delivering 108 leaflets an hour. Then you divide 405 by 108 and get 3.75, which is 3 hours and 3 quarters of an hour. since a quarter of an hour is 15 minutes it would be 3 hours 45 minutes.

Answer: x= -4

Step-by-step explanation: slope = (y2-y1)/(x2-x1).

(4-7)/(-7-x)

-3/-7-x=1

Multiply both sides by -7-x

-3=-7-x

Add 7 to both sides

4=-x so x = -4

 x  =  - 4x + 15             Change the ≤ to an = and solve for x    

4x =   4x          

5x  =       15

  x =    3           Now replace the equal sign with ≤

    x ≤ 3

Answer:

Well lucy has a 50/50 chance to get a odd card so that is it

Step-by-step explanation:

The ratio of even cards to odd cards that Lucy has is 3:4 in its simplest form.

Let's denote the number of even cards as "x" and the number of odd cards as "y".

The probability of choosing an even card is given as [tex]\frac{3}{7}.[/tex]

The probability of choosing an even card is calculated by dividing the number of even cards by the total number of cards:

Probability of choosing an even card = Number of even cards / Total number of cards

Therefore, we have:

[tex]\frac{3}{7} = \frac{x}{x+y}[/tex]

To find the ratio of even cards to odd cards, we can set up the equation:

[tex]\frac{x}{y} = \frac{3}{4}[/tex]

Therefore, the ratio of even cards to odd cards that Lucy has is 3:4 in its simplest form.
