Question

And some time of a day the length of the shadow of a tower is equal to its sides then sun's altitude at that time is?

Answer 1

HEY MATE YOUR ANSWER IS HERE

FIGURE IS REFFERED TO THE ATTACHMENT

SOLUTION :-

inin figure ab is a tower and BC is the length of the shadow it is given that length of the shadow of a tower is equal to its height

THEREFORE ,

BC = AB

1 = AB /BC

TAN 45 = AB/BC

HENCE SUN'S ALTITUDE IS 45°

Answer 2

$\huge\red{ \mathbb{SOLUTION}}$

$\sf\ \: Let \: the \: length \: of \: the \: shadow = x \: units \\ \\ \sf\ Height \: of \: the \: shadow = x \: units \\ \\ \bf\ Let \: the \: angle = A \degree\\ \\ \mathbb{Tan \: A = \frac{x}{x} } \\ \\ \sf\ \implies: Tan \: A = 1 \\ \\ \bf\ \implies: Tan \: A =Tan 45\degree \\ \\ \sf\boxed{ \implies: A = 45 \degree}</p><p>$
