Pentagonal Tiling 7

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