    (8,23 degrees) = (r, theta) r = 8 theta = 23 degrees ------------------------------ x = r*cos(theta) x = 8*cos(23) x = ??? y = r*sin(theta) y = 8*sin(23) y = ??? The answer will be in the form (x,y)

    all you have to do is evaluate 8*cos(23) and 8*sin(23) using a calculator

    All you have to do now is simply use your calculator. Make sure it's in degree mode. You can use the same method for the others

    You use the same exact method on the others. Well, the third one actually doesn't have a vertical component. But you probably already knew that.
