What are the a) x components of a verctor a in the xy plane if its direction is 250 degrees counterclockwise from the positive direction of the x axis and its magnitude is 7.3m?

b) the same question as above but for the y component of the vector a.

In the book it says that the answer for a) is -2.5m

b)-6.9m

I can't seem to get these answers. Can you help me?

Measuring the angle the way you specified:

xcomponent= Mag*cosTheta

Ycomponent= Mag*sinTheta

The book seems to be in agreement with this.
