(B) Let the height of the pole be $h$ and the length of the shadow be $x$.Given that the length of the shadow is equal to the height of the pole,we have $h = x$.In the right-angled triangle formed by the pole and its shadow,the angle of elevation $	heta$ is given by:$	an 	heta = \frac{	ext{Height of the pole}}{	ext{Length of the shadow}} = \frac{h}{x}$Since $h = x$,we get:$	an 	heta = \frac{h}{h} = 1$We know that $	an 45^{\circ} = 1$.Therefore,$	heta = 45^{\circ}$.

When the length of the shadow of a pole is equal to the height of the pole,then the angle of elevation of the source of light is: (in $^{\circ}$)
