**bobpursley**, Thursday, February 18, 2010 at 12:38pmI see in the triangle the following:

obtuse angle: 180-63.8, opposite side 106ft, another side 64.

Law of sines to get the guy angle:

64/sinA=106/sin(180-63.8)

solve for angle A.

Then, knowing angle A, you can find the third angle at the top between the guywire and the flagpole.

law of sines:

SinA/64=SinThirdAngle/how far

solve for how far.
