Step-by-step explanation:
1182.60 - 315 = 867.60
867.6 / 9640 = 0.09 = 9%
Answer:
150
Step-by-step explanation:
First a diagram which looks like a 12 sided figure where all the sides are equal.
Now draw 2 consecutive radii.
There are 12 such triangles in a 12 sided polygon.
These triangles have an apex angle of 360 / 12 = 30 degrees.
The other two angles making up the triangle are both equal. Therefore x + x + 30 = 180
2x = 150
x = 75
But 75 is 1/2 of the interior angle. There are 2 such angles making up the interior angle 75 + 75 = 150
Answer:
-2
Step-by-step explanation:
(1 , 3) = (x1 , y1)
(-2 , 9) = (x2 , y2)
slope = y2 - y2/x2 - x1
=9 - 3/-2 -1
=6/-3
=-2
Answer:
y+10=4(x-3)
