The sum of internal angles of a regular hexagon is 720 degrees. The value of angle B is 108 degrees.
What is a hexagon?
The hexagon can be defined as a polygon that has six sides and six angles. Hexagon has no curved sides and all the lines are closed.
The figure shows a hexagon that has six internal angles.
The value of angle B is calculated as given below.
[tex]\angle A + \angle B + \angle C + \angle D + \angle E + \angle F = 720^\circ[/tex]
[tex]170^\circ + \angle B + 133^\circ + 102^\circ + 117^\circ + 90^\circ = 720 ^\circ[/tex]
[tex]\angle B + 612^\circ=720^\circ[/tex]
[tex]\angle B = 108^\circ[/tex]
Hence we can conclude that the value of angle B is 108 degrees.
