So yes :P

a bunch of sine and cosine laws would work

not sure if there's a faster approach though

The section is law of cosines; im going to assume you only use that.
anonymous
  • anonymous
you could solve for the angle between 35 and d

how?;o

c^2=a^2+b^2-2abcosC
anonymous
  • anonymous
a=35, b=52, c=25 , solve for C

Angle theta is 60 because consecutive angles of a parallelogram are supplementary.

solve for alpha and you should be about to get the rest

c and d are the full lengths of the diagonals... right?
anonymous
  • anonymous
no its only half
Lukecrayonz
  • Lukecrayonz
wouldnt it just be 26?
anonymous
  • anonymous
your angle is wrong though, the 120 should be a 60
anonymous
  • anonymous
ignore the drawings, have no idea what i was thinking
anonymous
  • anonymous
but i got it now
anonymous
  • anonymous
(2d)^2=25^2+35^2-2(25)(35)cos60 (2c)^2=25^2+35^2-2(25)(35)cos120
