How many sides do 2 pentagons 3 nonagons and 2 hexagons have in all?
They have 49 sides.
How many sides do 2 pentagons and 5 decagons have in all?
There are (2*5) plus (5*10) = 60 sides
How many degrees are in a irregular decagon?
all decagons have 1440 degrees
How many faces have pairs of parallel edges in a decagonal based prism?
If the prism is based on regular decagons and it is a right prism, all 12 faces.
How many congruent sides does a polygon have?
It all depends on what kind of polygon it is. It may have no congruent sides or all congruent sides.
How many sides do 4 decagons 2 nonagons and 2 pentagons have altogether?
Each decagon has 10 sides, each nonagon has 9 sides and each pentagon has 5 sides. 4 decagons make 40 sides, 2 nonagons make 18 sides and 2 pentagons make 10 sides. When you add them all up together, you get 68 sides in total.
How many sides do 2 decagons 1 hexagon 4 nonagons and 2 triangles have altogether?
A decagon has ten sides, a hexagon has 6, a nonagon has nine, and a triangle has three. So 2 decagons, 1 hexagon, 4 nonagons, and 2 triangles have 2*10 + 1*6 + 4*9 + 2*3 = 20 + 6 + 36 + 6 = 68 sides altogether.
How many sides do 3 hexagons and 3 nonagons have altogether?
A hexagon has six sides, and a nonagon has nine. Three hexagons and three nonagons then have (3 x 6) + (3 x 9) = 18 + 27 = 45 sides altogether.
How many sides do 2 pentagons 3 nonagons and 2 hexagons have in all?
They have 49 sides.
How many sides does 5 hexagons 3 octagon and 2 decagons have in all?
There are 74 sides in all.
How many sides do 5 triangles, 1 octagon, and 3 decagons have in all?
There's 5 triangles but till 3 sides in each, in Hectagon is 8 sides and the 3 Decagons are still 10 sides on it.
How many sides do 2 pentagons and 5 decagons have in all?
There are (2*5) plus (5*10) = 60 sides
How many sides does a regular decagons have?
It still has ten sides, same as a normal decagon. "Irregular" simply means that all the sides and angles of the decagon are not congruent.
How many sides do 5 decagons and 5 hexagons have in all?
A decagon has 10 sides, and a hexagon has 6 sides. To figure out the total number of sides for 5 decagons and 5 hexagons:Number of Sides = 5(10) + 5(6)Number of Sides = 50 + 30Number of Sides = 80
How many sides do 4 decagons 4 heptagons and 3 octagons have altogether?
A decagon has ten sides, a heptagon seven, and an octagon eight. So in 4 decagons, 4 heptagons, and 3 octagons there are 4*10 + 4*7 + 3*8 = 40 + 28 + 24 = 92 sides altogether.
How many sides do 4 dodecagons 3 pentagons and 2 decagons have in all?
There are 12 sides in a dodecagon, 5 in a pentagon, and 10 in a decagon. So in 4 dodecagons, 3 pentagons, and 2 decagons there are 4*12 + 3*5 + 2*10 = 48 + 15 + 20 = 83 sides altogether.
What shape can be a 9 sided polygon?
All nine sided polygons are known as "nonagons". Nonagons that have all side lengths the same are known as "regular nonagons".
