A rotating beacon is located at point A next to a

A rotating beacon is located at point A next to a long wall. (See the figure to the right.) The beacon is 4 m from the wall. The distance a is given by a = 4| sec 2?t|, where t is time measured in seconds since the beacon started rotating. (When t = 0, the beacon is aimed at point R.) Find a for t = 0.37.a? meters(Type an integer or decimal rounded to one decimal place as needed.)
