Answer: 215.6 meters
Step-by-step explanation:
Formula of a polygon: A= 1/2ap
a = apothem
p = perimeter
Since the polygon has 7 sides, you need to multiply 7 by 7.7 (side length) to find the perimeter which would be 53.9
A= 1/2 x 8 x 53.9
A = 215.6 meters
Answer:
750
Step-by-step explanation:
150 x 5 = 750 and counts for Mon Tus Wes Thu Fri
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:
x + 7
Step-by-step explanation:
x2 + 4x − 21
set equal to 0
x2 + 4x − 21 = 0
factor
(x - 3) (x + 7)
x2 + 11x + 28
set equal to 0
x2 + 11x + 28 = 0
factor
(x + 4) (x + 7)
