This can be solve by using a triangle, because the path of the plane formed a triangle. first solve the angle form by the second direction

angle = 180 - 51 - 22 = 107 degrees

then using the cosine law

c^2 = a^2 + b^2 - 2ab cos C

c^2 = 76^2 + 123^2 - 2 (76) (123) cos (107)

c = 162.4 mi the crew fly to go directly to the field
