33. A property line AD instersects a simple curve at point B whose radius is 120 m. long. The azimuth of the property line is 300° while that back asimuth is 220°. A random line was run from the P.C. of the curve towards the property line which intersects at point A with an azimuth and distance of 190° and 42.50 m respectively. Compute the central angle of arc EB. ANS: 20°26'
