Answer:
This fact can be proved by solving the oblique triangle pli for the side pi using only ... A photograph of focal length 200 mm . is tilted 3° and needs to be reduced to 0 . 9 size . If the photograph is rectified ... Solution : cos b = 600 sin 3° • 200 = 0 . ... 4 mm . re = ( 200 • sin 3° ) [ ( sin 80° 58 0 = sin 79° 57 : 1 ) - cos 3° ] = ( 200 = 0 .
