An aerialist on a high platform holds onto a trapeze attached to a support by a 7.1-m cord. Just before he jumps off the platform, the cord makes an angle of 37° with the vertical. Calculate the angle θ that the trapeze cord makes with the vertical at the instant it is 0.61 m below its initial height.
A) 32.5°
B) 57.5°
C) 42.5°
