B. find the sine of the angle you found in part i. this is also 17pi/6
.

The answer to your question is: 1/2 or 0.5

Step-by-step explanation:

Data

Ф = ?

17π/6

Convert rad to degrees

                                 π rad   180°

                                 17π/6     x

                                  x = (17π/6 x 180) / π

                                  x = 510°

Now substract 360° from 510°

                                 510° - 360° = 150°

150° is in the second quadrangle, here sin is positive and also get the angle

as 180° - 150°

   Ф = 180° - 150°

       = 30°

 sin 30 = 1/2 or 0.5
