Three of exterior angle of n-sided polygon are 50° each two of it's interior angle are 127° and 135° and the remaining interior
irga5000 [103]

Answer:

The value of n is 21.

Step-by-step explanation:

We are given that three of the exterior angle of the n-sided polygon are 50° each two of its interior angle are 127° and 135° and the remaining interior angle are 173 each.

As we know that the sum of all exterior angles of the polygon is 360°. Also, the number of remaining interior angles will be (n - 5).

And, the exterior angle = 180° - the interior angle.

So, according to the question;

(3 \times 50) + (180-127) + (180 - 135) + (n - 5)\times (180-173) =360

150 + 53 + 45 + 7(n - 5) = 360

248 + 7n - 35 = 360

213 + 7n = 360

7n = 360 - 213

7n = 147

n = \frac{147}{7}

n = 21

Hence, the value of n is 21 and this is a 21-sided polygon.

Please help me. I will give brainliest.
Ber [7]

Hey!

------------------------------------------------

Points:

(-2, 3) and (3, 0)

------------------------------------------------

Find the slope:

= \frac{y2 - y1}{x2 - x1} \\=\frac{0 - 3}{3 - (-2)}\\= \frac{-3}{5} or -0.8

------------------------------------------------

Slope Intercept Form:

y = mx + b

m = slope

b = y-intercept

Slope = -3/5

Y-intercept = 9/5

Answer: y = -3/5 + 9/5

------------------------------------------------

Point Slope Form:

y - y1 = m(x - x1)

You can use either of the points.

Answer:

y - 3 = -3/5(x - 2)

          or

y - 0 = -3/5(x - 3)

------------------------------------------------

Hope This Helped! Good Luck!

Answer:

Center: the middle of the circle. Radius: the fixed distance from the center to any point on the circle is called the radius.

Step-by-step explanation:

The center is a fixed point in the middle of the circle; usually given the general coordinates (h, k). The fixed distance from the center to any point on the circle is called the radius.

<h3>Multiplication Property of Equality is the missing reason</h3>

<em><u>Solution:</u></em>

Given that,

five thirds times x plus 2 equals negative 3

Therefore,

\frac{5}{3}x + 2 = -3

<em><u>Multiplication Property of Equality</u></em>

The Multiplication Property of Equality means that, if both sides of an equation is multiplied by same number, the equation still remains equal

\frac{5}{3}x + 2 = -3

Multiply both sides by 3

3(\frac{5}{3}x + 2) = -3 \times 3\\\\5x + 6 = -9

<em><u>Subtraction Property of Equality</u></em>

The Subtraction Property of Equality means that, we can subtract the same number from both sides of equation and the equation will still be true

5x + 6 = -9

Subtract 6 from both sides

5x + 6 - 6 = -9  - 6

5x = -15

<em><u>Division Property of Equality</u></em>

The Division Property of Equality means that, if both sides of an equation is divided by same number, the equation still remains true

5x = -15

Divide both sides by 5

x = -3
