3. A and B are two points located on each bank of a river and near the abutments of a proposed bridge. To determine its distance, a baseline CD 180 m long was established on one bank of the river and the transit was set up at stations C and D and the azimuth were taken as follows: Azimuth LINE (degrees) 210°00' С - D C - A 260°00' 290°00' С -В D - A D - B 301°00' 315°00' 1. Find the distance AD.
