Step-by-step explanation:
u see,
the height of the airplane from the ground is 314m
but with the tower's horizontal plane, it would be
=> altitude of aircraft - height of tower
=> 314 - 70 = 244 m
now in the ABC,
using the ratio of sine,
sin 16 = AB/AC
=> 0.275 = 244/AC
=> AC = 244/ 0.275
=> AC = 887.9...
=> AC = approx. 886 meters
