Sum = 1440°

Each interior angle = 144°

Each exterior angle = 36°

Step-by-step explanation:

6) Sum of interior angles = 180(n - 2)°

where n = number of sides

For a decagon, the number of sides = 10

The sum of interior angles = 180(10 -2)

The sum of interior angles = 180(8) = 1440°

Each interior angle = The sum of interior angles/ number of sides

Each interior angle = 1440/10 = 144°

Sum of Exterior angles of a polygon = 360°

Each exterior angle = Sum of Exterior angles of a polygon/ number of sides

Each exterior angle = 360/10

Each exterior angle = 36°
