Pentagonal Tiling 9

A pentagonal tiling which vertices are labeled/labelled A, B, C, D and E.
2A^+C^=360°2\hat{A} + \hat{C} = 360\degree
D^+2E^=360°\hat{D} + 2\hat{E} = 360\degree
(2B^+C^+D^=360°)\left(2\hat{B} + \hat{C} + \hat{D}= 360\degree\right)
AB=BC=CD=DE\overline{AB} = \overline{BC} = \overline{CD} = \overline{DE}
