Question

If the ratio of the height of a tower and the length of its shadow is 1:√3, then the angle of elevation of the sun has measure ......
(a) 30
(b) 45
(c) 60
(d) 75

Answer 1

According to angle of elevation concept

$tan\alpha =\frac{height}{base}$

$here, \frac{height}{shadow} =\frac{1}{\sqrt{3}}$

hence, $\alpha = 30 degree$

option a is correct.
