Explanation:

Case 1: The given relation applies to consecutive angles

Consecutive angles of a parallelogram add up to  

180

Explanation:

In a parallelogram, there are only two sizes of angle - two are acute and two are obtuse.

Opposite angles are equal .

Consecutive angles are supplementary because they are co-interior angle on parallel lines.

An additional solution to the one given by Alan P is using the fact that the sum of the interior angles of a parallelogram is 360°.

Let one angle be  

x

The size of the other angle is given by  

9

x

−

30

2

x

+

2

(

9

x

−

30

)

=

360

←

sum of the angles is 360°

2

x

+

18

x

−

60

=

360

20

x

=

420

x

=

21

°

The obtuse angles are each  

180

−

21

=

159

°

The other option where the given angle is the opposite angle is described is well explained by Alan P.

Step-by-step explanation:

The interior angles of the parallelogram are 21° and 159° respectively.

What is parallelogram?

A parallelogram is defined as a quadrilateral in which both pairs of opposite sides are parallel and equal.

In a parallelogram opposite interior angles are equal and the angles on the same side of the traversal are supplementary (i.e) 180°

For the given situation,

The measure of one interior angle be [tex]x[/tex] and

Another angle was given as [tex]9x-30[/tex]°  

⇒[tex]x+9x-30[/tex]°[tex]=180[/tex]°

⇒[tex]10x=180[/tex]°[tex]+30[/tex]°

⇒[tex]10x=210[/tex]°

On dividing [tex]10[/tex] on both sides,

⇒[tex]\frac{10x}{10}=\frac{210}{10}[/tex]

⇒[tex]x=21[/tex]°

So, another angle is [tex]9x-30[/tex] = [tex]9[/tex]×[tex]21-30[/tex]

⇒[tex]189-30[/tex]

⇒[tex]159[/tex]°

Hence we can conclude that the interior angles of the parallelogram are 21° and 159°.

We can do it as per BODMAS rule.

[tex]5^{\dfrac{5}{2}}\times (\dfrac{20^{\dfrac{3}{2}}}{10^{-2}})\\\\=5^{\dfrac{5}{2}}\times {20^{\dfrac{3}{2}}}\times {10^{2}}\\\\=5^{\dfrac{5}{2}}\times {20^{\dfrac{3}{2}}}\times 100\\\\=5^{\dfrac{5}{2}}\times {(5\times 4)^{\dfrac{3}{2}}}\times 100\\\\=5^{\dfrac{5}{2}}\times {(5^{\dfrac{3}{2}})\times (4)^{\dfrac{3}{2}}}\times 100\\\\=5^{(\dfrac{5}{2}+\dfrac{3}{2})}\times 2^2^{\dfrac{3}{2}}\times 100\\\\=5^4\times 2^3\times 100\\\\=625\times 8\times 100\\\\=500000[/tex]

Answer:

B. f(x) = -x + 2

Step-by-step explanation:

First, you find the point on the y-axis which is (0,2) in this problem.

This will be your b in y = mx+ b

Then, you'll find how many blocks you are moving or rise over run. Which is -1/1 or -1.

This will be your m in y = mx + b

But we don't write the 1 so it will just be -x

Now add all your numbers in the standered form (y = mx + b) to get y = -x + 2 or f(x) = -x + 2

180-3x =x (corresponding angles are equal)

x=45°

11)180-5x=3x ( same reason)

x=10°

12)180-6x=3x(same reason)

x=20°

Answer: See explanation

Step-by-step explanation:

10) Same side interior angles add up to 180°

3x + x = 180

4x = 180

x = 45

11) Same side interior angles add up to 180°

5x + 3x = 180

8x = 180

x = 22.5

12) 6x is vertical to an angle that has a relationship with 3x (same side interior angles) which means 6x and 3x have to add up to 180° as well

6x + 3x = 180

9x = 180

x = 20

Step-by-step explanation:

Answer:  The answer is 475 cm long.

Step-by-step explanation:

Since his bedroom is 4.75 meters long, it would be 475 cm.

Answer:This is a linear equation.

y = mx+b

y is the total cost.

The slope m is the rate: that's 9 dollars per hour.

x is the number of hours.

b is the initial value: that's 16 dollars.

y = 9x+16

The problem states that the cost was 79 dollars.

Substitute that for y and solve for x.

79 = 9x+16

63 = 9x

x = 7 hour

Answer:

[tex]\frac{x(x-5)+3(x-5)}{x(x-7)+3(x-7)}[/tex]

[tex]\frac{(x+3)(x-5)}{(x+3)(x-7)}[/tex]

[tex]\frac{x-5}{x-7}[/tex]

Answer:

See bolded below

Step-by-step explanation:

1. First solve the inequality:

2|3-4x|+5>4 [subtract 5 from both sides]

2|3-4x| > - 1 [divide both sides by 2]

|3-4x| > - 1/2

Since all absolute values are always greater than or equal to 0, the solution would be: All Solutions. Respectively in interval notation we have (- ∞, ∞)

2. Start by solving the equation:

|2-3x|=|x-3|,

2-3x = x-3, 2-3x = -(x - 3)

x = 1.25, x = -0.5

In set builder notation: { x | x ∈ {1.25, -0.5} }
