They have 49 sides.
38 sides
A nonagon has nine sides and a pentagon has five sides. So 4 nonagons and 1 pentagon have 4*9 + 1*5 sides = 41 sides
'Hepta' from Latin for '7' means the polygon has '7' sides. Similarly 'nona' from Latin for '9' means the polygon has '9' sides. Simnce there are 1 heptagon and 2 nonagons. then the number of sides is 7 + 9 + 9 = 7 + (2x9) = 7 + 18 = 25 The answer!!!!!
1*6 + 2*4 + 4*10 + 3*9 = 6 + 8 + 40 + 27 = 81
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.
A nonagon has 9 sides and a triangle has 3. So there are (5*9)+(1*3) = 48 sides in 5 nonagons and 1 triangle.
Nonagons have 9 sides
A heptagon has seven sides, a nonagon has nine, and a quadrilateral has four. So in 2 heptagons, 3 nonagons, and 3 quadrilaterals there are: (2*7)+(3*9)+(3*4) = 14 + 27 + 12 = 53 sides altogether.
9 of them, as well as 9 angles.
Nonagons.
Nonagons.
enneagons or nonagons
A heptagon has seven sides, a hexagon six, a nonagon nine, and an octagon eight. So in 5 heptagons, 2 hexagons, 4 nonagons, and 3 octagons there are (5*7)+(2*6)+(4*9)+(3*8) = 35 + 12 + 36 + 24 = 107 sides altogether.
A dodecagon has 12 sides, a nonagon has 9, and quadrilateral has 4, and a triangle has 3. So in 1 dodecagon, 2 nonagons, 1 quadrilateral, and 4 triangles there are 1*12 + 2*9 + 1*4 + 4*3 = 12 + 18 + 4 + 12 = 46 sides 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.
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.
