Answer:

45 degrees.

Step-by-step explanation:

The exterior angle = sum of the 2 opposite interior angles.

2x =  x + 45

2x - x = 45

x = 45.

Answer:

x = 45 degrees

Step-by-step explanation:

<u><em>The measure of exterior angles is equal to the sum of non-adjacent interior angles</em></u>

=> 2x = x+45

=> 2x-x = 45

=> x = 45 degrees

Name the property used to make the conclusion. If x+ 3 = 17, then x = 14 -
zimovet [89]

Answer:

Subtraction property of inequality

Step-by-step explanation:

Step 1: Definition of Subtraction property

Subtraction property of equality refers to balancing an equation by using the same mathematical operation (minus) on both sides.

Step 2: Relate the definition above with the given question.

It can be seen from the statements in the question that 3 was subtracted from both sides of the initial equation to get:

x + 3 = 17 \\ x + 3 - 3 = 17 - 3 \\  x = 14

Write an equation of the line in slope-intercept form
Agata [3.3K]

Answer:

y=2x-2

Step-by-step explanation:

Slope intercept form = y=mx+b

Where m=slope and b= y intercept

Reminder: the y intercept is where x=0

Looking at the graph, the y intercept is given as (0,-2)

There are also two points given (0, -2) and (2,2)

Reminder: to find the slope, divide the changes in y by the changes in x or substitute the numbers into this equation: y2-y1/x2-x1

2-(-2)/2-0=4/2

m=2

Now that we have the slope and y intercept, sbstitute into the equation y=mx+b:

y=2x-2

Consuelo's living room is in the shape of a rectangle and has an area of 360 square feet. The width of the living room is 5/8 it
uranmaximum [27]
<h2>Therefore the length of the living room = 24 ft</h2>

Step-by-step explanation:

Given that , Consuelo's living room is in the shape of rectangle and has an area of 360 square feet and the width of the living room is \frac {5}{8}   its length

Let ,the length of the living room is = x ft

Then width =\frac {5}{8}x ft

Therefore the area of the living room =x \times \frac {5}{8}x ft^2

According to problem,

x\times \frac {5}{8}x = 360

⇔\frac{5}{8}x^2=360

⇔x^2 = \frac{360\times 8}{5}

⇔x^2 = 576

⇔x=\sqrt{576}

⇔x = 24

Therefore the length of the living room = 24 ft
