An aerialist on a high platform holds on to a trapeze attached to a support by an 8.00-m cord. (See the drawing.) Just before he jumps off the platform, the cord makes an angle of 41.0° degrees with the vertical. He jumps, swings down, then back up, releasing the trapeze at the instant it is 0.750 m below its initial height. Calculate the angle θ that the trapeze cord makes with the vertical at this instant.
