Answer:
(1,-1)
Step-by-step explanation:
This is an octagon, which has 8 sides.
the angle of rotation is 360/8 = 45°
There are two -main- approaches to answer this problem. By using the sine identity, or applying law of sines.
We'll do the sine trig. identity, as it is the most effective.
Given an angle '
' in a right triangle, '
' is defined as the opposite side of the triangle to the given angle, over the triangle's hypotenuse.
So, for this setup:
Now, we solve for x:
So, answer is 3.4
A=πr2
A=3.14 x 6 x 6
answer=113.04
