Answer: What does this mean?
<u><em>Step-by-step explanation: WHAT THE DOES THIS MEAN ????????!!!!!</em></u>!
Neither because if he has 2 cylinders/surfaces and a cube/point he cuts the cylinders and now has 4 surfaces and a cube has 4 points ( 4 surfaces 4 points )
Answer:
y = 2x - 3
Step-by-step explanation:
x + 2y = 4
2y = -x + 4
y = -1/2x + 2
1 = 2(2) + b
1 = 4 + b
-3 = b
y = 2x - 3
The answer is distributive property :)
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.)
