A large weather balloon is tethered by two ropes. One rope measures 22ft and attaches to the balloon at an angle of 33° from the ground. The second rope attaches to the base of the balloon at an angle of 17° with the ground. How far from the ground is the balloon floating? Round intermediate values to four decimal places, then round the final answer to the nearest tenth of a foot. The balloon is floating approximately  ft  from the ground.
