If the cosine of an angle is 0.93475, what is the angle expressed as degrees, minutes and seconds?
cos(x) = 0.93475 Take the cos^-1 of each side to solve for x
because the cos^-1(cos(x)) = x
check that your answer will be 20deg 48min 43.94 sec
20 degrees 48 minutes 43.9 se
@mark_o. how is degrees and time related?
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.
have two more i need checked
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.
what is the cosine of 104.73167 degrees? i got -0.25429 is this correct
yes correct @ krissywatts
what is the tangent of 75 degrees 16 minutes abd 31 seconds? i got 3.80508
