Question

The diagram below shows an angle, 0, graphed in the xy-coordinate plane. The segment RT is the initial side of the

Answer 1

The coordinating sine value for this angle of rotation will be 4.189.

How to calculate the angle?

From the complete information, in the unit circle, there's a point with -1/2 and the x value is 240°.

In this case, the coordinating sine value for this angle of rotation will be:

= (240 × π)/180

= (240 × 3.142) / 180

= 4.189
