6.15549

#cos 17pi/12 = cos 255=-0.2588

#sin 17pi/12= sin 255 =-0.9659

In cartesean coordinates the first point would be #(3 cos 17pi/12, 3 sin 17pi/12)# Or,(-0.77645, -2.89777)

Second point would be #(5cos 7pi/8, 5 sin 7pi/8)#,

Or, (-4.6194,1.9134)

Apply distance formula to get the distance= 6.15549.
