cos(x) = 0.93475 Take the cos^-1 of each side to solve for x

because the cos^-1(cos(x)) = x

@mark_o. how is degrees and time related?
anonymous
  • anonymous
it's not time, it's just the same sort of terminology. a degree can be divided into 60 parts called "minutes", and each minute can be divided into 60 seconds.

So it's very much like time, but it is just a way of dividing up degrees.

its not really time here,,its the revolution , like i revolution = 360 degrees, and measurements with minutes and seconds are subdivisions of degrees having nothing to do with time. The names are due to the fact that 1/60th was chosen as the standard, so there are sixty minutes in a degree and sixty seconds in a minute, just like on a clock.
