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.

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 triangles is there in a decagon?
There are 8 triangles in a decagon
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 can make a decagon?
10 triangles make a decagon
How many triangles in an decagon?
A decagon can have eight or more triangles - up to infinitely many.
How many sides do 1 decagon and 3 octagons have altogether?
An octagon has 8 sides. A decagon has 10. So 3*8+10 = 34 sides
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 triangles is there in a decagon?
There are 8 triangles in a decagon
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 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 has decagon?
There are 8 triangles inside a 10 sided decagon
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.
