the resulting displacement of the OB aircraft is determined by the cosine theorem

“OB^2=OA^2+AB^2-2 cdot OA cdot AB cdot cos(180^0-22.5^0)”

“OB^2=209^2+100^2-2 cdot 209 cdot 100 cdot cos(157.5^0)”

“OB^2=43681+10000-2 cdot 209 cdot 100 cdot (-0.924)”

“OB^2=43681+10000+39877.2”

“OB^2=93558.2”

then

“OB=sqrt{93558.2}=305.873km”
