- trigonometry HARD!! -
**Reiny**, Tuesday, May 4, 2010 at 8:35pmfind the two distances:

northbound part = 234.6(40/60) = 156.4 miles

NE part = 252(20/60) = 84 miles

N 20°31' E = N 20.5166667 ° E

I see a triangle with sides 156.4 and 84 with an angle of 159.48333 between them.

by cosine law

x^2 = 156.4^2 + 84^2 - 2(156.4)(84)cos 159.48333

= ...

I will let you slug it out

(I got 236.9 miles)
