Answer:

Assuming you want this rounded to the hundredths.

6. x = 24.86

7. x = 4

8. x = 24.86

9. x = 12

10. x = 4

11. x = 20.57

Step-by-step explanation:

6. Because these angles are supplementary, they add up to 180 degrees. Using this, we can solve for x.

Step 1: Build your equation

3x + 5 + 4x + 1 = 180

Step 2: Combine like terms

7x + 6 = 180

Step 3: Subtract 6 from both sides of the equation.

7x = 174

Step 4: Divide the coefficient of x out.

x ≅ 24.68

7. Vertical Angles Theorem states that vertical angles are congruent. Now we can solve from there!

(Note: There are two ways to solve this, but I picked the easier way)

Step 1: Build your equation

3x + 5 = 4x + 1

Step 2: Collecting like terms on one side 1: Subtract 3x from both sides

5 = x + 1

Would you look at that! No coefficient on x. However, we need a sequel to fix the right side.

(If you are wondering why there is no coefficient on x, the actual coefficient is 1. However, it is much cleaner to just ignore that.)

Step 3: Collecting like terms on one side 2: Subtract 1 from both sides.

4 = x

Because equations don't care about silly human things like which terms are on which side, you can also arrange it like this:

x = 4

8. A linear pair of angles are adjacent angles formed by two intersecting lines. The measure of a linear pair of angles is 180 degrees. See #6 for details on how to solve this.

9. Complementary angles add up to 90 degrees. Similar to supplementary angles, this can be solved but setting the sum to 90 degrees.

Step 1: Build your equation.

3x + 5 + 4x + 1 = 90

Step 2: Combine like terms.

7x + 6 = 90

Step 3: Subtract 6 from both sides of the equation.

7x = 84

Step 4: Divide the coefficient of x from both sides.

x = 12

10. Because they are congruent, you can set the angles equal to eachother. Please view #7 for how to solve this.

11. Similiar to #6 and #9, we can set the sum to 150 degrees and solve from there.

Step 1: Build your equation.

3x + 5 + 4x + 1 = 150

Step 2: Combine like terms.

7x + 6 = 150

Step 3: Subtract 6 from both sides of the equation.

7x = 144

Step 4: Divide the coefficient of x from both sides.

x ≅ 20.57

There you have it! Wow, I haven't done algebra like that since 2019!

Hope I helped!

Use the scale factor to compare the perimeter and area of the original figure of the enlarged figure. Complete the statements ab

Reika [66]

Answer:

Part 1) The scale factor is 2

Part 2) The perimeter of the enlarged rectangle is 19 units

Part 3) The area of the enlarged rectangle is 19.5 square units (the area of the enlarged rectangle is 4 times the area of the original rectangle)

Step-by-step explanation:

we know that

A dilation is a non-rigid transformation that produce similar figures

If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

The ratio of its perimeter is equal to the scale factor and the ratio of its areas is equal to the scale factor squared

step 1

Find the scale factor

Let

z ---> the scale factor

$z=\frac{3}{1.5}=2$

step 2

Find the perimeter of the enlarged rectangle

Multiply the perimeter of the original rectangle by the scale factor

The perimeter of the original rectangle is

$P=2(1.5+3.25)=9.5\ units$

so

The perimeter of the enlarged rectangle is

$9.5(2)=19\ units$

step 3

Find the area of the enlarged rectangle

Multiply the area of the original rectangle by the scale factor squared

The area of the original rectangle is

$A=(1.5)(3.25)=4.875\ units^2$

so

The area of the enlarged rectangle is

$4.875(2^2)=19.5\ units^2$

The area of the enlarged rectangle is 4 times the area of the original rectangle

step 4

Find the value of b

Multiply the corresponding side of the original rectangle by the scale factor

$b=3.25(2)=6.50\ units$

Verify the perimeter of the enlarged rectangle

$P=2(3+6.50)=19\ units$ ----> is ok

Verify the area of the enlarged rectangle

$A=3(6.50)=19.5\ units^2$ ---> is ok
