Question

Please I really need help

Answer 1

85°

Explanation:

The two angles are known as vertical angles, which are always congruent

Answer 2

∠DEB = 85°

Explanation:

Vertical Angle Theorem

When two straight lines intersect, they form two pairs of angles. The vertically opposite (non-adjacent) angles are congruent.

Angles AEC and DEB are vertically opposite angles, therefore:

∠AEC = ∠DEB

As ∠AEC = 85° then ∠DEB = 85° also.
