Answer:
a 5-point star has rotational symmetry. A 5-point star is a two-dimensional polygon in the shape of a star with five points, or tips.
So symetry will have a total of 360 degrees, then if you divide it by 5 ( the number of point in the star) you will get 72 degrees each so it has 5 reflections
Y is 12 you just multiply by 2 since 15 was multiplied by 2 as well
Answer:
B
Step-by-step explanation:
A (w2-18=16)(w2-18=16) so, 16+16=32 (no)
B (w2+18=20)(w2-18=16) so, 20+16=36 (yes)
C (w2-6=4)(w2-6=4) so, 4+4=8 (no)
D (w2+6=8)(w2-6=4) 6+4=10 (no)
