15.        7i()/2 =  6300 

16. The first segment of the slide = 15/sin(20degrees) =43.85

the third segment of the slide =15/sin(30 degrees) =30

the middle segement = 110 - 15/tan(20 degrees)-15/tan(30 degrees)  =110-41.21-25.98=  110-67.19=42.81

Total slide =43.85+30+42.81 =116.66

17. Period=4

18.sec(-180) =sec(180) =  -1

19. the height =210 * tan(63 degrees)=412.85 ft
