Question

1. A pole and its shadow have same length , find the angle of the sun ray made with the earth at that time​

Answer 1

Answer:

45°

Step-by-step explanation:

let angle be θ.

tan θ = opp. / adj. = 1

=> θ = 45°

Answer 2

$\huge{\green {\underline {\underline {\mathfrak {Answer}}}}}$

The angle made by the sun ray is 45°.

$\huge{\green {\underline {\underline {\mathfrak {Explanation}}}}}$

Given,

Height of pole = Height of shadow

Now,

$\tan \alpha = \frac{</strong><strong>AB</strong><strong>}{</strong><strong>BC</strong><strong>}$

Since AB = BC,

Hence,

$tan \: \alpha = \frac{</strong><strong>AB</strong><strong>}{</strong><strong>AB</strong><strong>} \\ tan \: \alpha = 1 \\ tan \: 45</strong><strong>°</strong><strong> = 1$

•°• The angle made by the sun ray is 45°.
