Question

mertsj · Answer

$$138^{o}23'=138 \frac{23}{60}^{o}=138.38333...^{o}$$

mathmale · Answer

In your shoes, here's what I'd do:
(1) convert 138 deg 23 min to degrees alone.
(2) find the sine of the resulting angle (with calculator in Degree mode).
(3) find the reciprocal of the result from (2).

mertsj · Answer

Find the sin of that angle and take the reciprocal

mathmale · Answer

Mertsj has generously taken care of (1), and has proposed the same procedure as I from that point on.  Thanks.

Did you take the reciprocal?

anonymous · Answer

how do u convert it tho?

mertsj · Answer

You have a 1/x button on you calculator.  Find it and use it.

mertsj · Answer

Or just divide 1 by the number you posted.

mathmale · Answer

Mertsj has shown exactly what is necessary for the conversion.  See his post, above.

That 1/x button takes the RECIPROCAL (not the conversion) of the sine of the angle in question.
