Convert Angle measure to Degrees Minutes Seconds
I am given -0.335 (no degree sign)

I am told that the answer is -20 degrees 20 minutes 24 seconds.

If I convert -0.335 as a degree I get -0 degrees 20 minutes 6 seconds

If I change -0.335 to degrees I get -19.19408614 degrees then when I convert to Degrees minutes seconds, my answer is -19 degrees 11 minutes 38.71 seconds.

How do I have to approach this so that -0.335 turns into --20 degrees 20 minutes 24 seconds

Prove It
Are you sure you're not asked to find $\displaystyle \sin^{-1}(-0.335)$ and then convert to DMS?

yea, even if I take inverse sine of -.335 to get the degree of -19.57253794. That still does not give me the answer that I am told. Haven't worked with inverse yet. The directions say: use the angle-conversion capabilities of a graphing utility to convert the angle measure to D M'S" form.

I figured out the problem I had thank you. To get the same answer you need to solve the same problem. The problem read -.355
