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 Answer: Option D
Explanation
In (bigtriangleup)KBC, sin 30 = (frac{800}{IKCI})
IKCL = (frac{800}{sin30^o})
= (frac{800}{0.5})
= 1600m
