Answer:
Option B. 24/25
Step-by-step explanation:
we know that
In the right triangle DEF
∠D+∠E=90° -----> by complementary angles
so
sin(D)=cos(E)
we have
sin(D)=24/25
therefore
cos(E)=24/25
The distance is increasing at a rate that is the speed of the plane multiplied by the cosine of the angle between its flight path and the direct line to the radar station. That cosine is 4/√(3²+4²) = 4/5, so the distance is increasing at
440 mi/h × 4/5 = 352 mi/h
