how do you find the degrees of P?

**Reiny**, Tuesday, December 16, 2008 at 7:51pmsince it is a unit circle, that is the radius is 1, then P can be written as (cos,sin)

then cos = .3420

then angle = 70

notice you would get the same if you took

sin = .9397

= 70 and notice that

.3420^2 + .9397^2 = 1
