SO A=63 a=17 B=? b=18 C=? c=? using law of sines sine 63/17=sinB/18 SinB= sin63x18/17 ---------------' B=70.6 degrees ' ---------------' to find C C= 180-63-70.6 ----------------' C= 46.4 degrees ' ----------------' using law of cosines
so it would be c^2=a^2+b^2-2ab cos C 900^2+1260^2-2(900)(1260)(cos75) c^2=33542.9 c=183.14km is it right?
how does B= 27.3 how did u come up with that number
