Answer: 1080 degrees
Step-by-step explanation:
Since the general formular is
(n - 2 )180 = interior angle.
Where n is the number of sides the polygon has.
Octagon has 8 sides so therefore n= 8.
(8-2 ) * 180
= 6 * 180
=1080.
The total number of the interior angles measured is 1080 degrees.
y=−3x+9 slope of this equation is -3 and y-intercept is 9
Plot the y -intercept first which is 9 and mark the points using the slope which is -3. Join the points. So blue line in the graph is y = -3x+9
y=−x−5 slope of this equation is -1 and y intercept is -5
Plot the y -intercept first which is -5 and mark the points using the slope which is -1 . Join the points. So pink line in the graph is y = -x-5
The intersection point of these two lines gives you the solution.
The coordinates of point of intersection (7,-12)
It would cost $896 to plate fencing around the garden
In one year, $ 9,000 with a profit of 7.75%, is $ 697.5
697.5 × 18 = 12555
After 18 years old, it is $ 15,222
