Sorry, I messed those two up

$67^{\circ} 30' = 67 + \frac{1}{2} \implies (\frac{135}{2})^{\circ}$

Is there only one cos in your question @IloveCharlie

you can check that b is a nearly answer.

12. IloveCharlie

Yes, @waterineyes, only one cos

13. IloveCharlie

Can I get more help for this one? sin67degrees 30'= a., b., c., or d.?

14. IloveCharlie

yes

17. IloveCharlie

Can you please show me how you got that?

yes sin67+30/60 0.920+1/2 0.920+0.5=1.42

19. IloveCharlie
