The formula for working out the total interior is:
180(n-2) = 1260
So let’s rearrange by dividing both sides by 180 and find what n is:
n-2 = 7
Then let’s add 2 to both sides to find what n is:
n=9
Each interior angle is 1260/9 = 140°.
The sum of the interior angle and its corresponding exterior angle is 180°.
Therefore, the polygon has 9 sides. :)
Answer:
22
Step-by-step explanation:
This is a right angle so the sum of those would be equal to 90 degrees
x + 7 + 3x - 5 = 90 add like terms
4x + 2 = 90 subtract 2 from both sides
4x = 88 divide both sides by 4
x = 22
Answer:
Horizontal axis
Step-by-step explanation:
By convention, the independent variables is arrayed along the Horizontal axis (abscissa) in a scattergram.
The stcattergram has two dimensions
- The X (independent) variable is arrayed along the horizontal axis.
- The Y(dependent) variable is arrayed along the vertical axis.
- Each dot scattergram is case in data set.
- The dot is placed at the intersection cases scores on X and Y.
Your answer is B. -125 4/27
