tan 60 = x/40
tan 60*40 = x
x= 69.282
tan 30 = x/40
tan 30*40 = x
y= 23.094
69.282 - 23.094

tan 45 = 28/x
28/tan 45 = x
x = 28
tan 60 = 28/x
28/tan 60 = x
x = 16.1658
Distance between

30 degrees
tan 30 = 120/x
120/tan 30 = x
x = 207.846
60 degrees
tan 60 = 120/x
120/tan 60 = x
x = 69. 282
207.846 - 69.282 = 138.564
distance between = 138.564
