Since the golden ratio is approximately 1.618033989 which fits what you provided, then rounded to the nearest thousandth would be 1.618
m<M + m<N = 180°
11x + 6x - 7 = 180
11x + 6x = 180 + 7
17x = 187
x = 187 : 17 = 11
m<M = m<O = 11x = 11 · 11 = <span>121°
</span>m<N = m<L = 6x-7 = 6 · 11 -7 = 66 - 7 = <span>59°
</span><span>Check : 121° + 59° = 180° OK !
</span>
