The length of a shadow of a tree in 8 metres long when the sun's angle of elevation is 45° is 8 m

Step-by-step explanation:

Height of tree = 8 m

Let the length of shadow be x

Angel of elevation = 45°

ATQ

$Tan \theta = \frac{Perpendicular}{Base}\\Tan 45^{\circ}=\frac{8}{x}\\1=\frac{8}{x}\\x=8$

Hence The length of a shadow of a tree in 8 metres long when the sun's angle of elevation is 45° is 8 m
