Yes but how do I find the degree of the other angle i need to get AC?
OHHH okay :D then just multiply the solution from that by 17 for the cost?
yahhhhh. :D for part a i got 196.717… is that what you gots? :)
ches ches (: now part c, i just say… ?
YAYYYY ooh i like part C~! :D
kay, so now you know the value of BD because you gots it in the first part.
and so you can use the law of SINES now. ^^
sooooo sin115/BD = sinABD/70
plug in BD, and you should prooooob get 18.8 for ABD
Oh yeah i forgot that for paper 2 they will look at your work. okay gotcha! then just find the height of ABD then multiply by the base!
yeppp. u know how to find the height doe?
I did it today for paper 1. Like i drew the height, made it 90 degrees, then added 18.8 then subtracted the sum from 180. Then i used that angle to do the law of sine, then multiplied the height times the base c:
YAYYYYY smart cookieehhh~! hahahaaaa
kay, then just multiply the area by 120 for partE.
