Answer:
The sum of the interior angle is 108°
Step-by-step explanation:
To find the sum of the interior angle, you need this equation:
(The variable represents the number of sides does a shape have).
-Count the sides of the shape:
The following polygon shown, has 5 sides.
-After you have the number of sides of the polygon, use the number of sides for the equation and it will be written as:
-Then, you solve:
So, the sum of the interior angle is .
If it is a parallelogram, then AC = BD. Therefore we have the equation:
5x + 4 = 3x + 8 <em>subtract 4 from both sides</em>
5x = 3x + 4 <em>subtract 3x from both sides</em>
2x = 4 <em>divide both sides by 2</em>
x = 2
BD = 3x + 8
Put the value of x:
BD = 3(2) + 8 = 6 + 8 = 14
<h3>Answer: 14</h3>
6.
the y-intercept is 4, which means the line crosses the y-axis at the point (0,4).
[just put a dot on the number four that's right under the letter y]
the slope of the line is positive, so it goes up from left to right.
Start at the y-intercept. Move up 2 and then move right 1.
You are now at the point (1,6).
[go to 1 for the horizontal line, then go up 6 spaces.] [connect two points]
7. y= -1/2-3
8. y=3x+4
