d2 = 3h * 300mi/h @ 15deg=900km@15deg.

Da = d1 - d2 = Distance apart.

Da = 1200km@258 = 900km@15deg. =

X = hor.=1200cos258 - 900cos15=-1119mi.

Y=ver.= 1200sin258 - 900sin15=-1407mi

tanA = Y/X = -1407/-1119 = 1.2574.

A = 51.5 deg.

A = 51.5 + 180 = 231.5 Deg.

Da = -1119 / cos231.5 = 1798mi apart.
