Answer 1

0.9212 (Answer b)

Explanation:

Note that sin 52 deg 47 min = sin (52 47/60 deg)

Using the fact that pi radians = 180 degrees, convert the argument of the sine function to radians:

sin ( [52 47/60][pi rad][180 deg] )

= sin ( 0.2932 pi) = 0.9212

Using a calculator to evaluate this, we get 0.2891
