See attachment.
<br>Angle MCL = beta/2
<br>Angle LOB = 90 -beta/2
<br>
<br>HI = radius*sin(90-beta/2) = 0.5*cos(beta/2)
<br>GH = GI - HI
<br>GI = A - FG = 3 - 1.0625 = 1.9375
<br>=&gt; GH = ML = GI - HI = 1.9375 - 0.5*cos(beta/2)
<br>
<br>JM = 0.5*cos(90-beta/2) = 0.5*sin(beta/2)
<br>MK = radius - JM = 0.5 - 0.5*sin(beta/2)
<br>MC = KC - ...
