Question

At some time of the day the length of the shadow of a tower is equal to its height find the sun's altitude at the time

Answer 1

HEY MATE YOUR ANSWER IS HERE..

according to given attachment ab is pole and BC should be Shadow are equal at sometime of the day ..

$\frac{ab}{bc } = tan \: theta \: \\ \\ ab \: = \: bc \: = x \\ \\ \frac{x}{x} = tan \: theta \: \\ \\ 1 = tan \: theta \: \\ \\ tan \: 45 = tan \: theta \: \\ \\ thea \: = 45 \: degree$

THANKS FOR UR QUESTION HOPE IT HELPS

Answer 2

Step-by-step explanation:

Given : THE length of the shadow of the tower is equal to its height.

AB = BC

Tanthetha = 45°

tan thetha = ab/bc

tan thetha = ab/ab

tan thetha = 1

so thetha = 45°
