230-180 = 50.

2*angle for rotation = 50*2 = 100.

So 230-100 = 130 answer.

The rotation angle is 360 - 230 = 130.

Shopiyaan Dhas said: (Jul 13, 2016)  
230 + 130 = 360 -> Angle of rotation.

Angle of rotation is 50 or 130.

Explain it clearly.

Kaviyaprema said: (Feb 7, 2018)  
Angle of rotation is 360.
It swings 230.
Remaining angle to be rotated is 130(Angle of Rotation).

In Photogrammetry, the angle of rotation = swing- 180.
So,
Answer will be = 230 -180 = 50.
