A waterpark slide covers 100 feet of horizontal space and is 36 feet high. A new replacement slide will create an angle with the water surface that measures twice that of the original slide. The new slide will use the same horizontal space as the old slide. What is the height of the new slide to the nearest foot? (Enter only the number.)

tan(theeta)=36/100
Theeta= tan1(36/100)
Angle= 19.7
