Answers:

  • In the top row, the first and third polygons are regular polygons.
  • In the bottom row, only the first polygon is a regular polygon

============================================================

Explanation:

A regular polygon must have all sides of equal length. Also, all angles must be the same measure. This applies to the equilateral triangle in the upper left corner, and the square in the upper right corner. Each angle of the square is 90 degrees even though your teacher didn't use right angle markers.

The middle figure in the top row is not a regular polygon because the sides are not all the same length. Also, the angles are different.

--------------------

In the bottom row, only the first figure is a regular polygon for similar reasons mentioned earlier. The second figure is not a regular polygon because this figure is concave. Only convex polygons can be regular.

The third figure in the bottom row is not regular because one side is longer than the others.

The formula for perimeter of a rectangle is given by p = 2l + 2w, where p = perimeter, l = length, and w = width. solve the form
TiliK225 [7]
Perimeter formula
p = 2l + 2w

I reverse left-right side
2l + 2w = p

Move 2l to the right
2l + 2w = p
2w = p - 2l

Move 2 to the right
2w = p - 2l
w = (p - 2l)/2

Summary
p = 2l + 2w
2l + 2w = p
2w = p - 2l
w = (p-2l)/2

An Angle measures 64 more than the measure of its supplementary angle what is the measure of each angle
ValentinkaMS [17]

Answer:

Original angle = 122*

Supplementary angle = 58*

Step-by-step explanation:

A supplementary angle is one of two angles that make up 180*

If one angle is 30*, its supplementary angle is 150*. 30 + 150 = 180.

So in this case we have two angles, the original and the supplementary angle. The original angle is 64* more than the supplementary angle. The key word is MORE.

The formula to figure it out would look like this:  x + (x + 64) = 180

x is the supplementary angle

x + 64 is the original angle (64 MORE than its supplementary angle)

180 is the total measure of the two angles because they are supplementary and we know that supplementary angles always equals 180* when added together.

Take the formula and do a little algebra.

x + (x + 64) = 180

Subtract 64 from both sides

x + x = 116

Combine the x's

2x = 116

Divide both side by 2

x = 58

Remeber we know that the original angle is 64 more than the supplementary angle, so we'll add the 64 to the value of x and we get 122.

x + 64 = 122

Check our work:

x + (x + 64) = 180

58 + 58 + 64 = 180
