Answer: x= cd/5 + 9/5
Answer:
j = -8
Step-by-step explanation:
-13j - 20 = -8j + 20
Add 13 j to each side
-13j+13j - 20 = -8j+13j + 20
-20 = 5j+20
subtract 20 from each side
-20-20 = 5j +20-20
-40 = 5j
Divide by 5
-40/5 = =5j/5
-8 =j

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°
