Sin(45 degrees) / Sec(110 degrees)
Help I need to know how to solve this.

Sin(45 degrees) / Sec(110 degrees)

How can I solve this? If I get a step by step example I might be able to solve the other 9 problems before morning... I need to know how for a test I am going to take tomorrow. Please help...

What do you mean solve this? Find the exact value?

sec(110) = 1/cos(110) => 1/sec(110) = cos(110) ........

So the value is sin(45) cos(110).

You should know the exact value of sin(45).

Are you sure it's 110 degrees and not 120 degrees?

I am not sure turn it into something else maybe radians I am not sure. I only have these on my notes on what I should study, the only thing I wrote was solve...

I need to see this one "solved" so I can have an idea on how to answer questions like this on the test.

Yes its 110 none of the questions here have more then 1 with a value like 30 45 60 90 120 etc.

Also what do I do after I get the radians?

such as Sine 45 is PI/4 how do I combine it with whatever 110 cos will give?

Edit: Help anyone.....

Edit: Help... I am going to sleep I'll wake up early to see if anyone answered this for me before I go take the test...
