A regular octagon has all its eight sides congruent. The line segments joining each of the vertices of a regular octagon to its center are called the radii of the octagon. These 8 radii divide a regular octagon into 8 congruent isosceles triangles. Area of each isosceles triangle is
,
where a is length of the side of the octagon and
is the angle between two radii of the octagon.
In regular octagon
.
Then the area of regular octagon is
sq. m.
Answer:
sq. m.
Answer:
Answer is Lee Ann wrote the right equation.
Step-by-step explanation:
2/8 equals 25%, which equals 1/4, half of 25% is 12.5%, so 25% plus 12.5% equals 37.5%.
37.5% in decimal form is 0.375.
Therefore Lee Ann is correct.
Answer:

For this case m represent the slope and is given by
and from the other condition given we know that
. And replacing we got:

And if we reorganize the terms we have:

And subtracting 3 in both sides we got:

Step-by-step explanation:
For this case we have the following function y=g(x) and we want to find the tangent line to this function using the conditions: 
So we need a function like this one:

For this case m represent the slope and is given by
and from the other condition given we know that
. And replacing we got:

And if we reorganize the terms we have:

And subtracting 3 in both sides we got:
