The angle of elevation of an aircraft from a point K on the horizontal ground 30(\alpha). If the aircraft is 800m above the ground, how far is it from K?

A
400.00m
B
692.82m
C
923.76m
D
1,600.99m

Correct Option: D

In (\bigtriangleup)KBC, sin 30 = (\frac{800}{IKCI})

IKCL = (\frac{800}{sin30^o})

= (\frac{800}{0.5})

= 1600m
