Explicație pas cu pas:

<D + <E + <F + <G = 360°

D + 60%<D + 80%<D + 30%<D = 360°

100%<D + 60%<D + 80%<D + 30%<D = 360°

270%<D = 360°

270*<D/100 = 360°

<D = 100*360°/270 = 400°/3

400° : 3 = 399°60' : 3 = 133°20'

<D = 133°20'

<E = 400°/3*60/100 = 80°

<F = 400°/3*80/100 = 320°/3

320° : 3 = 318°120' : 3 = 106°40'

<F = 106°40'

<G = 400°/3*30/100 = 40°
