An Exterior angle is the angle formed by a rectilinear figure's side and a neighbouring side that is stretched outside. The measure of the sixth exterior angle will be 80°.
What is an exterior angle?
An Exterior angle is the angle formed by a rectilinear figure's side and a neighbouring side that is stretched outside.
The sum of the exterior angles of a polygon is equal to 360°. Therefore, the measure of the sixth exterior angle can be written as,
52° + 56° + 65° + 54° + 53° + x =360°
x = 360° - 280°
x = 80°
Hence, the measure of the sixth exterior angle will be 80°.
