What must be the lengths of the wood?

Golden ratio; The ratio of the smaller to the larger is equal to the ratio of the larger to the whole.
G = = .618....
a = the longer line
b = the shorter
a + b = 120
b + .618a
therefore
1.618a = 120
a = 120/1.618
a = 74.1656" the longer length
b = 120 - 74.1656
b = 45.8344" the shorter
