Answer:
G.) 72°
Explanation:
A regular pentagon has all it's sides equal.
And all it's internal angles = 108°
The sum of all it's internal angles= 540°
AEB = TRIANGLE
And sum of internal angles In a triangle= 180°
EBDC is quadrilateral and a quadrilateral has it's internal angles summed up to 360°
But DEB = CBE
Let DEB = X
x + x +108+108= 360
2x= 360-216
2x= 144
X= 144/2
X=72
DEB = 72°
