What are the lengths of side AB and side BC?

What Are The Lengths Of Side AB And Side BC?

Answers

Answer 1

Answer: AB=20, BC=14

Step-by-step explanation:

set AB together with the side congruent to it (which is DC)

3x-7=x+11

subtract x and add 7 to both sides

2x=18

divide both sides by 2

x=9

plug 9 in for AB.

3(9)-7

27-7=20.

now do the same for BC

Answer 2

Answer:

AB = 20

BC = 14

Step-by-step explanation:

ABCD is a parallelogram

Opposite sides of a parallelogram are equal.

Therefore,

AB = DC

3x - 7 = x + 11

3x - x = 11 + 7

2x = 18

x = 18/2

x = 9

AB = 3x - 7 =3*9 - 7 = 27 - 7 = 20

7y - 7 = 3y + 5

7y - 3y = 7 + 5

4y = 12

y = 12/4

y = 3

BC = 7y - 7 = 7*3 - 7= 21 - 7 = 14

Answer:

1. m<rsv is 42 degrees

2.

Step-by-step explanation:

1.

2. Since abc is 95, the two angles you have to solve are going to equal 95 when added because they make up the angle ABC so solving it would be like

(2x+23)+(9x-5)=95 you then solve this which would be

2x+23+9x-5 = 95 - Combine like terms

11x+18=95 Subtract 18 both sides

11x=77 divide by 11

x=7

After this you just put 7 in the equations instead of X and solve it

Is the equation 96 ÷ 3 = 72 ÷ 2 true or false?
True
False

Answers

Answer:

false

Step-by-step explanation:

96/3=32

72/2=36

The answer to this equation for 96/3=24
Because if you want to check do 24(3)=96

Now you’re doing 24/2 which equals to 12 also to check do 12(2)=24, therefore this equation is false

Will mark brainlyest if correct.

Answers

Answer: The scale factor from the first map to the second map is 4:3 (four to three) The side lengths of the landmark on the second map is 9/4 mm, 3 mm, 15/4mm.

Step-by-step explanation:

The scale factor is 8:6 which can be simplified to 4:3.

The side lengths of the landmark on the second map follows the same scale 4:3, so going in order:

4:3 = 3:x

4x = 9

x = 9/4

4:3 = 4:y

y = 3

4:3 = 5: z

4z = 15

z = 15/4

Answer:

y=-3x+2

y = [tex]\frac{1}{5}[/tex]x - 5

Step-by-step explanation:

Question 1

It is given that;

- one of the lines has an equation of; y = -3x-7

- the given line's y-int is (0, 2) ~(The y-int is when the line crosses the y axis, hence x is zero)

- these two lines are parallel

When two lines are parallel, their slope is the same, hence  the equations of the given line would look like this;

y = -3x + 2

In the slope-intercept format (which is; y = mx + b, where "m" is the slope, and "b" is the y-intercept).

Questions 2

It is given that;

- one of the lines has an equation of y = -5x + 1

- the given line's y-int is (0, -5) ~(The y-int is when the line crosses the y axis, hence x is zero)

- these two lines are perpendicular

When two lines are perpendicular, their slopes are the negatives reciprocal of each other, hence the equations of the given line would look like this;

y = [tex]\frac{1}{5}[/tex]x - 5

In the slope-intercept format (which is; y = mx + b, where "m" is the slope, and "b" is the y-intercept).

[tex]\frac{1}{3}[/tex] feet

Step-by-step explanation:

The area of a rectangle is represented by the formula [tex]A = l[/tex] ×[tex]w[/tex], in which [tex]A[/tex] is the area, [tex]l[/tex] is the length, and [tex]w[/tex] is width.

Let's put in what we already know into the formula. We know that the area is [tex]\frac{5}{18}[/tex], so let's substitute that for [tex]A[/tex]. We know that the length is [tex]\frac{5}{6}[/tex], so let's substitute that for [tex]l[/tex]. This gives an equation that looks like this:

[tex]\frac{5}{18} = \frac{5}{6}[/tex] × [tex]w[/tex]

To find the width, all we need to do know is isolate [tex]w[/tex]:

[tex]w = \frac{5}{18}[/tex] × [tex]\frac{6}{5}[/tex]

[tex]w = \frac{30}{90}[/tex]

[tex]w = \frac{1}{3}[/tex]

Thus, the width is [tex]\frac{1}{3}[/tex].

A plot of land is in the shape of a triangle. Two of the angles measure 48 degrees and 74 degrees. The length of the side between them is 90 m.


a) calculate the perimeter of the plot, to the nearest meter.

b) calculate the area of the plot, to the nearest square meter.

Answers

Answer:

Perimeter = 271 meters

Step-by-step explanation:

third angle measure would have to be 180 - 122 = 58 degrees

you can use the law of sines:

sin 58° = sin 74°

   90           b

.85 = .96

 90       b

cross-multiply:  .85b = 86.4

                          b = 102

now do again to find third side:

sin 58° = sin 48°

   90           c

.85 = .74

 90       c

.85c = 67

c = 79

now you know all 3 sides so add them to get perimeter (79+102+90) = 271
