Question #084dc

Answer 1

See explanation.

Explanation:

To convert an angle from degrees to radians tou have to multiply it by `pi/180`.

Here we have:

`32^o30^'=32.5^o`

Now we can transfer it to radians:

`32.5^o=32.5xxpi/180=32.5/180 pi=65/360pi=13/72pi`

Finally we can add the minus sign:

`-32^o30^'=-13/72pi`
