Please help me with #7
Dominik [7]

Step-by-step answer:

This is a regular heptagon, means it has 7 <em>congruent</em> sides and 7 <em>congruent </em>vertex angles.

To work with polygons, there is a very important piece of information that you must know to solve the majority of related problems.

This is:

sum of exterior angles of polygons = 360 degrees.

If you don't remember the 360 degrees, think of the sum of exterior angles of an equilateral triangle, which is 3*(180-60)=3*120=360!  It works!

For a regular heptagon, c = 360/7=51.43 degrees approx.

This means that each vertex angle measures

vertex angle = 180-c

So since 2d+the vertex angle = 360, we have

2d+(180-c)=360

solve for d:

2d=360-(180-c)=180+c

d=(180+c)/2=90+c/2=115.71 degrees. (approx.)

Which figures can be precisely defined by using only undefined terms? Select three options.
love history [14]

This is a pretty bad question but I think the answer they're looking for is

angle

circle

line segment

We define arcs in terms of circles and parallel lines in terms of lines (though not necessarily line segments, so this is a bit of a judgement call).

What is the value of the expression 8−2 ?<br><br><br> 64<br><br> 116<br><br> 164<br><br> −16
GenaCL600 [577]

Any number to the power of a negative integer will be 1 over that number with the absolute value of the power, so it looks like this:

x^{-2} = \frac{-1}{x^{2}}

Therefore, you just need to 8² which is 64, and then do 1 over that (1/64) because it's a negative power.
