A man's eye level is 1.7m above the horizontal ground and 13m from a vertical pole. If the pole is 8.3m high, calculate, correct to the nearest degree, the angle of elevation of the top of the pole from his eyes.
A
33o
B
32o
C
27o
D
26o
correct option: c
tan (\theta = \frac{opp}{adj} = \frac{6.6}{13})
tan (\theta = 0.5077)
(\theta) = tan-1 0.5077
(\theta = 27^o)
