Answer:
1). Fold reflection symmetries = 5
2). Order of rotational symmetries = 10
3). Smallest angle of rotational symmetry = 36°
Step-by-step explanation:
A decagon has number of fold reflection symmetries = 5
[Fold reflection symmetries are the lines by which we can fold the shape into half]
Order of rotational symmetry of a decagon = 10
[Order of rotational symmetry means number of rotations by which the polygon maps itself in a complete rotation of 360°]
Smallest angle of rotational symmetry for a decagon
= 
=
= 36°
it is 870 cm tall
(That is the correct answer)
Answer:
104 in²
Step-by-step explanation:
look at the picture above... by splitting the figure, we get two rectangles.
a1= 5×4 = 20in²
a2= 12×7= 84 in²
total area = a1+a2 = 20+84=104in²
