There are 8 triangles in a decagon

A decagon has 10 sides, and a hexagon has 6. So in 4 decagons and 5 hexagons there are (4*10)+(5*6) = 70 sides

10 triangles make a decagon

A decagon can have eight or more triangles - up to infinitely many.

There are 8 triangles inside a 10 sided decagon

A decagon has 10 sides

A decagon has 10 sides

A decagon has ten sides and a triangle has three, so 5 decagons and 4 triangles have (5*10)+(4*3) = 62 sides altogether.

There are 10 sides on a decagon

10 triangles

120 triangles.

10-2 = 8 triangles

A decagon has 10 sides

There are: (5*6)+(3*5)+(5*3) = 60 sides

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.

Its not a do-decagon its a dodecahedran!!

4 hexagons; A hexagon has 6 sides, thus, if you have 4 hexagons, 4x6=24

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

A decagon has ten sides, a quadrilateral has four, an octagon has eight, and a triangle has three. So in 1 decagon, 5 quadrilaterals, 5 octagons, and 5 triangles there are 1*10 + 5*4 + 5*8 + 5*3 = 10 + 20 + 40 + 15 = 85 sides altogether.

A decagon has 10 sides, and a quadrilateral has 4 sides, therefore a decagon has 6 more sides than a quadrilateral.

One hexagon has six sides, so 100 hexagons have 600 sides.
