Are you allowed to use your calculator? If so, plug this into your calculator as : $-(1/\cos((7\pi)/10))$. Make sure you're in radian mode. You will get approximately 1.7013.

4. First tell me

Hi!Dave19
ok first tell me if you know how to calculate the value of sin(18) where 18 is in degree.(I am asking this so that my answer may not become a new question for you).I think you want to calculate the value manually.please let me know about this also.

5. I Just Need It In Steps For On The Calculator.

i guess i would like you to show me putting it into degrees because the question before it was just tan 124.36 degrees so go ahead.
