The angle between their flight paths is 75 degrees after three hours, how fart apart are they?

answer:

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?

**drwls**, Sunday, May 25, 2008 at 1:03amRight equation, but you did not do it correctly.

c^2 = 810,000 + 1,587,600 - 587,002

= 1,809,998

c = 1345 km
