precal

posted by .

A kite flier wondered how high her kite was flying. She used a protractor to measure an angle of 36 degrees from level ground to the kite string. If she used a full 140-yard spool of string, how high, in feet, was the kite? (Disregard the string sag and the height of the string reel above the ground.)

Round your answer to three decimal places.

Height = ___feet
