The ratio of the length of arod and its sha dow is 1 :root 3 The of elevation of sun is​

Answer 1

$\bold\green{\underline{QUESTION:}}$

The ratio of the length of arod and its sha dow is 1 :root 3 The of elevation of sun is

$\bold\green{\underline{Given:}}$

The ratio of the length of rod and it's shadow 1:√3

$\bold\green{\underline{Find: elevation\:of\:sun}}$

$\bold\orange{\underline{Solution:}}$

$\bold\purple{\underline{Let:}}$

The angle of elevation be angle ACB=theta

in which AB is rod and AC is it's shadow

$\bold\green{\underline{A.T.Q:}}$

We know ,that

In Triangle ACB tan theta=AB/CB

⟹Tan theta=1/√3

⟹Tan theta=Tan30°

⟹theta=30°

Hence,

$\bold\orange{\underline{The\:angle\:of\: elevation\:of\:sun=30}}$

Answer 2

answer: the angle of sum of elevation is equal to 30

Step-by-step explanation:

tan theta is equal to to 1 by root 3

tan theta is equal to Tan 30 degrees therefore sum is equal to 30
