Answer:

[tex]\angle AE = 32^{\circ}[/tex]

[tex]\angle EAD = 212^{\circ}[/tex]

[tex]\angle BE = 133^{\circ}[/tex]

[tex]\angle BCE = 227^{\circ}[/tex]

[tex]\angle AED = 180^{\circ}[/tex]

[tex]\angle BD = 79^{\circ}[/tex]

Step-by-step explanation:

The central angle of a circle is equal to 360º, whose formula in this case is:

[tex]\angle AB + \angle BC + \angle CD + \angle DE + \angle EA = 360^{\circ}[/tex]

In addition, the following conditions are known from figure:

[tex]\angle BC = 47^{\circ}[/tex], [tex]\angle DE = 148^{\circ}[/tex]

[tex]\angle DE + \angle EA = 180^{\circ}[/tex]

[tex]\angle CD + \angle DE = 180^{\circ}[/tex]

[tex]\angle AB + \angle BC + \angle CD = 180^{\circ}[/tex]

Now, the system of equations is now solved:

[tex]\angle EA = 180^{\circ}-\angle DE[/tex]

[tex]\angle EA = 180^{\circ}-148^{\circ}[/tex]

[tex]\angle EA = 32^{\circ}[/tex]

[tex]\angle CD = 180^{\circ}-\angle DE[/tex]

[tex]\angle CD = 180^{\circ}-148^{\circ}[/tex]

[tex]\angle CD = 32^{\circ}[/tex]

[tex]\angle AB = 180^{\circ} - \angle BC - \angle CD[/tex]

[tex]\angle AB = 180^{\circ}-47^{\circ}-32^{\circ}[/tex]

[tex]\angle AB = 101^{\circ}[/tex]

The answers are described herein:

[tex]\angle AE = 32^{\circ}[/tex]

[tex]\angle EAD = 212^{\circ}[/tex]

[tex]\angle BE = 133^{\circ}[/tex]

[tex]\angle BCE = 227^{\circ}[/tex]

[tex]\angle AED = 180^{\circ}[/tex]

[tex]\angle BD = 79^{\circ}[/tex]
