What unit is used to measure resistance

What is the measure of each interior angle of a regular octagon

135 Each interior angle of a regular octagon measures 135 degrees.

What is the sum of the interior angle measures of an octagon

1,080

What is the measure of each interior angle of a regular nonagon

A regular nonagon is a shape with 9 equal sides, right? Well, with the equation (n-2)180, where n is the number of sides, you can find the sum of the interior angles. Then you divide that number by n to get the measure of each interior angle. You do the rest.

If your in A+:140'

How many degrees are in the sum of an interior angle and an exterior angle of a regular hexagon

180

What is the sum of the exterior angle measures of a regular decagon

It is generally accepted to count only one vertex per side when calculating the sum of exterior angles. If this is what you mean, then for every convex polygon (all angles point away from center), the sum is always 360º.

However, you can also count two vertexes per side, so the sum would then be double, or 720º.

If the sum of the measures of two angles is 90 the angles are this

Find the area of an equilateral triangle that has a perimeter of 21 inches Round the answer to one decimal place

Find the area of an equilateral triangle that has a perimeter of 21 inches. Round the answer to one decimal place.

What is the measure of each exterior angle measure of a regular 18-gon

360/18 = 20 degrees

Which of these solids has eight faces

octahedron

What is the value of x if the perimeter is 75 feet

A+ =7

If the exterior angle of a regular polygon equals 72 degrees what shape is the polygon

Pentagon A+

Which of these two regular polygons has the larger interior angle triangle or heptagon

heptagon

Which of these two regular polygons has the larger exterior angle

A+:

  • Square
  • triangle

* * * * *

More like Z-.

A square does not have a larger exterior angle than an interior one - they are both 90 degrees. The ONLY regular polygon with the required property is an equilateral triangle.

Either pair of base angles of an isosceles trapezoid forms a pair of congruent angles.

If the interior angle of a regular polygon equals 120 degrees what shape is the polygon

120

Find the measure of arc DB

A+ = 82.

* * * * *

It depends on what measure you want: the angle subtended or the length of the curved segment, and also on what information you do have.

If five angles of a heptagon have measures 80 85 175 90 and 140 degrees and if the other two angles are congruent what is the measure of each of the other two angles

Which of these two regular polygons has the larger exterior angle Square Or Pentagon

Square = 90 degrees

Pentagon = 72 degrees

This figure is a regular 12-sided polygon Find m 3

Calculate the measure of a central angle of a regular ten-sided polygon.

Each interior angle of a regular 10 sided decagon measures 144 degrees

If two angles are vertical then they are nonadjacent angles formed by two intersecting lines. 2. If two angles are not vertical then they are not nonadjacent angles formed by two intersecting lines.

No. The non-vertical angles need not be related to one another in any way.
