Question

the ratio of the length and shadow of a post is 1:1. then the angle of elevation of the sun is​

Answer 1

Answer:

$let \: ab \: be \: the \: pole \: and \: bc \: be \: the \: shadow \: \\ \\ given \: = \frac{ab}{bc} = \frac{1}{ \sqrt{3 } } \\ \\ let \: acb \: the \: angle \: of \: elevation \: \\ \\ in \: triangle \: abc \: \\ x = theta \\ \\ \tan(a) = \frac{ab}{bc} \\ = \frac{1}{ \sqrt{3} } \\ \tan(x) = \tan(30) \\ x = 30 {}^{.} \\ \\ the \: angle \: of \: elevation \: = 30 {}^{.}$
