Two bicyclists, starting at the same place, are riding toward the same campground by different routes. One cyclist rides 1120 m due east and then turns due north and travels another 1550 m before reaching the campground. The second cyclist starts out by heading due north for 1800 m and then turns and heads directly toward the campground. (a) At the turning point, how far is the second cyclist from the campground? (b) What direction, measured as a positive angle relative to due east, must the second cyclist head during the last part of the trip?
