A man 40m from the foot of a tower observes the angle of elevation of the tower to be 30o, Determine the height of the tower
A
40m
B
40\(\sqrt{3}\)m
C
20m
D
\(\frac{40\sqrt{3}}{3}\)
correct option: d
tan 30o = (\frac{h}{40m})
h = 40 tan 30o
= 40 x (\frac{1}{\sqrt{30}})m
by rationalizing
h = (\frac{40\sqrt{3}}{3})m
