D=27 E=81 F=72
105 degrees
Angle "A" is congruent to Angle "D"
It can have any value in the range (0, 180) so it can be acute, right or obtuse.
In a parallelogram adjacent angles are supplementary, so angles are 75 degrees (A & C) and 105 degrees (B & D).
To determine if angle ABC is similar to angle DEF, we need to check if their corresponding angles are equal. If angle A corresponds to angle D, angle B corresponds to angle E, and angle C corresponds to angle F, and they all have the same measures, then angle ABC is similar to angle DEF. Otherwise, they are not similar. Without specific angle measures, we cannot conclude similarity.
In an obtuse triangle, the orthocenter is located outside the triangle. For triangle CDE, if angle CDE is obtuse (greater than 90 degrees), the orthocenter will be situated outside of the triangle, specifically in the direction of the obtuse angle. This is a distinctive property of obtuse triangles, contrasting with acute and right triangles where the orthocenter lies inside or at a vertex, respectively.

I assume that points BC is a straight line and that D is the point where the line DE intersects BC. If this is so, and CDE is 55 degress, then BDE is 125 degrees.
you are a dummy!
L perhaps
20% = 72 degrees
acute
just search cde cuteness on google
Obtuse if that's not the type of answer your looking for then GOOGLE it
One thing...CDE iS aWESOME! xD and it is.. sea love
