How many sides do 5 decagons and 4 triangles have altogether?
A decagon has ten sides and a triangle has three, so 5 decagons and 4 triangles have (5*10)+(4*3) = 62 sides altogether.
How many sides does 5 hexagons 3 octagon and 2 decagons have in all?
There are 74 sides in all.
How many sides do 3 decagons and 5 triangles have altogether?
There are ten sides in a decagon and three sides in a triangle. So in 3 decagons and 5 triangles there are 3*10 + 5*3 = 30 + 15 = 45 sides altogether.
How many triangles are there in an octagon?
There are six triangles in an octagon. In any convex polygon, there are two less triangles than the number of sides. So a octagon which has 8 sides, contains 6 triangles.
Is a polygon is an octagon?
If the octagon is a regular octagon (all eight sides and all eight angles are equal), then it is a regular polygon. If it is not a regular octagon (i.e. if it is an irregular octagon) then is it an irregular polygon.
How many sides do 3 decagons and 5 octagons have altogether?
A decagon has ten sides and an octagon has eight, so in 3 decagons and 5 octagons there are (3*10)+(5*8) = 30 + 40 = 70 sides altogether.
How many sides do 5 decagons and 5 octagons have altogether?
A decagon has 10 sides and an octagon has 8. 5*8 + 5*10 = 90 sides
How many sides do 4 decagons 5 heptagons 5 nonagons and 1 octagon have altogether?
A decagon has 10 sides, a heptagon has 7, a nonagon has 9, and an octagon has 8. So 4 decagons, 5 heptagons, 5 nonagons, and 1 octagon have 4*10 + 5*7 + 5*9 = 1*8 sides = 40 + 35 + 45 + 8 = 128 sides
How many triangles make an octagon?
There are 6 triangles in an octagon
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 triangles make up an octagon?
Eight triangles of equal size form a regular octagon.
How many sides do 2 nonagons and 2 decagons have in all?
38 sides
