Answer:
Angle CDE equals 155 degrees :D
Step-by-step explanation:
parallel lines
since the left angle is 57, angle BAE is also 57
180-57=123
right angle=90
115+90+123+57=385
540-385=155
thus, angle CDE equals 155 degrees
This object has rotational symmetry because if you made a partial turn it would still be the same all around, it doesn't have line symmetry tho because you couldn't draw a line through it and have it equal on both sides
Answer:
this is your answer. thanks!!
