A helicopter hovers at an altitude that is $$d = 979$$ feet above a mountain peak of altitude 5,184 feet, as shown in the figure. A second, taller peak is viewed from both the mountaintop and the helicopter. From the helicopter, the angle of depression is $$43 ^ { \circ }$$ , and from the mountaintop, the angle of elevation is $18 ^ { \circ }$ . Approximate the altitude of the taller peak.
A) 5,437 ft
B) 5,439 ft
C) 5,441 ft
D) 4,931 ft
E) 5,443 ft
