So, alot of people had trouble with that worksheet. Let's all post our problems down below, and then maybe we can work out the problems... For instance does anyone know how to get the TWO angles for number three? In the 3rd class we worked out one way (which I will post later tonight), but I don't think anyone's really sure about it... Also for number three how can C be an acute angle if it is a right triangle and c=hyp?
For number four I don't think anyone in the room during 3rd prd. knew how to do it, what is "n?" That was one of the big problems...

I had exactly the same problems you did! Please post if you know how to do the problems because I have no idea how to even begin question 4.
ReplyDeleteOkay, so for number three I just used the equation that he gave us... I think that Andrew figured out how to find the second angle... But I didn't understand it... If someone from 3rd period were to help out then that would be cool.
ReplyDeleteAnd yeah, number four destroyed me. Haha, no one knew where to begin in my class.
with the second angle we used the equation he gave us, but instead of using Sin, we used COS instead. We didn't really know if that was right but it just gave us another option. hopefully that helps.
ReplyDelete4 was just....4. We'll ask about it tomorrow.
don't use cos. use the reference angle of 56.4 instead. it's the same process as a reference angle of say 120, just with different numbers.
