1) Sin 36= a/25

a=25 sin 36

a= 14.69

Cos 36= b/25

b= 25 Cos 36

b= 20.23

----------------------

2) Sin 43= y/25

y= 25 sin43

y= 17.05

Cos 43= x/25

x= 25Cos 43

x= 18.28

----------------------

3) s= 42.58

  r= 177/Cos 20

  r= 124.51

hope it helps...

have a great day!!

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
