<h2>Answer:</h2>

option: b is the correct answer.

b. The adjacent angles formed by two intersecting lines are supplementary.

<h2>Step-by-step explanation:</h2>

Clearly from the figure that is given to us we could see that we are given measures of the adjacent angles (i.e. the angle that have a common vertex and a common side)

Hence, also by the given measures we have:

135°+45°=180°.

160°+20°=180°

130°+50°=180°

This means that the adjacent angles formed by two intersecting lines are supplementary ( since the sum of the two angles is 180°)

Hence, option:b is correct.

Answer: b. The adjacent angles formed by two intersecting lines are supplementary.

Step-by-step explanation:

In the given picture , we can see that there are intersecting lines with adjacent angles which have shown.

If we add the adjacent angles for each pair of intersecting lines we get,

$135^{\circ}+45^{\circ}=180^{\circ}$

$130^{\circ}+50^{\circ}=180^{\circ}$

$160^{\circ}+20^{\circ}=180^{\circ}$

Therefore,b is the right option "The adjacent angles formed by two intersecting lines are supplementary."

Two Angles are supplementary when their sum is 180 degrees.

Two Angles are complementary when their sum is 90 degrees.
Vertical angles are always equal.

Complete the work to find the dimensions of the rectangle. x(x – 3) = 10 x2 – 3x = 10 x2 – 3x – 10 = 10 – 10 (x + 2)(x – 5) = 0

Norma-Jean [14]

Answer:

$Length =5$

$Width = 2$

Step-by-step explanation:

Given

$Length =x$

$Width = x -3$

$Area = 10$

$x(x-3) =10$

See comment for missing part of the question

Required

Complete the expression to determine the dimension of a rectangle

We have:

$x(x-3) =10$

Open bracket

$x^2 -3x = 10$

Equate to 0

$x^2 -3x - 10 =0$

Expand

$x^2 + 2x - 5x - 10 = 0$

Factorize

$x(x + 2) - 5(x + 2) = 0$

Factor out x + 2

$(x - 5)(x + 2) = 0$

Solve for x

$x - 5 = 0$ or $x + 2 = 0$

$x = 5$ or $x = -2$

The value of x cannot be negative

So:

$x = 5$

Recall that:

$Length = x$

$Width = x - 3$

So:

$Length =5$

$Width = 2$ ---- i.e. 5 - 3

Arlene wants to create a scale drawing of the poster shown below:

Nostrana [21]

1/3 of the dimensions means to divide the dimensions by 3. This is to figure out what 1/3 of the dimensions are.
Our length is 6, and our width is 9.
Let's divide our length first.
6/3 = 2.
Our length with 1/3 of it's original dimensions is 2.
Let's divide our width now.
9/3 = 3.
Our width with 1/3 of it's original dimensions is 3.
Our dimensions are 2 by 3.
Your answer is A.) 2 in. by 3 in.
I hope this helps!

Find the greatest common factor of the following monomials 26n5 12n2

Sidana [21]

The greatest common factor is 2 $n^{2}$

We first have to look for the largest number that goes into both equations. The factors of 12 are 1, 2, 3, 4, 6 and 12. None of 3, 4, 6, or 12 go into 26 evenly. So 2 is the largest number you can take out.

With the variables, we take out as many as the lowest number will let us. Since the smallest number of n's is 2 in the second term, we take that many.

Which ordered pairs is a solution to -5x + 3y > 12?

GaryK [48]

9514 1404 393

Answer:

(-5, 5), (2, 8), (-6, 0)

Step-by-step explanation:

It is convenient to graph the solution, then plot the points to see which fall in the solution area.

The point (3, 9) falls on the boundary line, which is <em>not</em> part of the solution set.

The points that are solutions are ...

B(-5, 5)

E(2, 8)

F(-6, 0)
