1. If the platform has been turning for 25 seconds, it has moved through an angle of 225° and is in the third quadrant of its cycl a. Use a diagram like the one shown here to find the value of sin 225° based on the coordinate definition of the sine function. First choose a specific value for r. Then find the value of y using the right triangle.
