Answer:
since there are 18 of these isosceles triangles in the polygon, then multiply this by 18 to get area of the polygon with 18 sides is equal to 28.56497087 square units. you can round this to as many desimal digits as required. each of those little triangle with a vertex angle of 20 degrees is an isosceles triangle.
The last two choices are appropriate.
Both give you f(1) = 7, f(2) = 9.50, f(3) = 12.00, ... as they should.

5
Step-by-step explanation:
10-(2+3) = 5
Answer:
(-7,2)
Step-by-step explanation:
The point (7,-2) when reflected across the x-axis becomes (7, 2). When it is reflected across the y-axis it becomes (-7,2). You can find this because when a point is reflected across the x-axis, its y-coordinate changes its sign. The same is true when reflected across the y-axis. It's x coordinate changes its sign.
A double reflection across both axis changes the sign of each coordinate.
