An aerialist on a high platform holds onto a trapeze attached to a support by an 8.7-m cord. (See the drawing.)

He jumps, swings down, then back up, releasing the trapeze at the instant it is 0.79 m below its initial height. Calculate the angle0 that the trapeze cord makes with the vertical at this instant.
