The sum of the measures of the interior angles of a polygon with n sides is

defon

ANSWER

$(n - 2) \times 180 \degree$

EXPLANATION

The sum of the interior angles of a triangle is 180°

We can rewrite this as:

$1 \times 180 \degree = (3 - 2) \times 180 \degree = 180 \degree$

The sum of interior angles of a quadrilateral is 360°

We can also rewrite this as:

$2 \times 180 \degree = (4- 2) \times 180 \degree = 360 \degree$ In general an n-sided polygon has

the sum of the interior angles given by the formula:

$(n - 2) \times 180$

3x - y = 2<br>and<br>2x + y = 4

Naddik [55]

$\frac{3}{1}$ Answer:

Step-by-step explanation:

3x-y = 2

2x+y =4

put them into slope intercept form

y=3x-2

y=-2x+4

Now, you can either graph it or use substitution

3x-2 = -2x+4

+2x +2x

5x -2 = 4

+2 +2

5x = 6

5x/5 = 6/5

x = 6/5

3x -2 = y

3(6/5) -2 = y

3 x 6 / 1 x 5 = 18/5

3 3/5 -2 = 1 3/5

Let me know if it's wrong.

Hope this helps

If 2x - 3 = 3x - 7, what is the value of x?

icang [17]

Answer:

x=4

Step-by-step explanation:

2x-3=3x-7

Subtract 2x from both sides of the equation

-3=x-7

Add 7 to both sides of the equation to isolate x
