Answer 2

The length of the shade of a tree 12 meters tall is 12 m

Step-by-step explanation:

If the angle of elevation of the Sun is 45 °, find the length of the shade of a tree 12 meters tall.

Refer the attached figure :

Height of tree = AB = 12 m

The angle of elevation of the Sun is 45 °

Let the length of shadow i.e. BC be x

In ΔABC

$Tan \theta =\frac{Perpendicular}{Base}\\Tan45^{\circ}=\fraxc{AB}{BC}\\1 = \frac{12}{x}\\x=12$

Hence The length of the shade of a tree 12 meters tall is 12 m
