Answer:

  • 8) 76°
  • 9) 88°

Step-by-step explanation:

  • <em>Sum of exterior angles of any polygon is 360°</em>
<h3>Exercise 8</h3>

<u>Sum of given angles:</u>

  • 2x + 60° + 64° + 36° + 48° = 360°
  • 2x + 208° = 360°
  • 2x = 360° - 208°
  • 2x = 152°
  • x = 76°
<h3>Exercise 9</h3>

<u>Sum of given angles:</u>

  • x + 90° + 109°+ 73° = 360°
  • x + 272° = 360°
  • x = 360° - 272°
  • x = 88°

What is the midpoint between (3, -1) and (7, -5)?<br> Group of answer choices
Hatshy [7]

Answer:

The answer is

<h2>( 5 , - 3)</h2>

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

<h3>M = (  \frac{x1 + x2}{2} , \:  \frac{y1 + y2}{2} )</h3>

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(3, -1) and (7, -5)

The midpoint is

M = ( \frac{3 + 7}{2}  , \:  \frac{ - 1 - 5}{2} ) \\  = ( \frac{10}{2}  \: , \:  -  \frac{6}{2} )

We have the final answer as

<h3>( 5 , - 3)</h3>

Hope this helps you

Follow the process of completing the square to solve 2x2 + 8x - 12 = 0. After adding B2 to both sides of the equation in step 4,
Sladkaya [172]

Answer:


Step-by-step explanation:

I dont quite understand the problem but this is one way to solve it using completing the square:-

2x^2 + 8x - 12 = 0

2(x^2 + 4x) - 12 =  0

2((x + 2)^2 - 4)  = 12

2(x + 2)^2 - 8 + 8 = 12 + 8

2(x + 2)^2 = 20
