Math Problem Statement
An aerialist on a high platform holds onto a trapeze attached to a support by an 6.7m cord. Just before he jumps off the platform, the cord makes an angle of 42 degrees with the vertical. He jumps, swings down, then back up, releasing the trapeze at the instant it is 0.71m below its initial height. Calculate the angle that the trapeze cord makes with the vertical at this instant.
