To find out the length of the shadow of a tower, given the altitude of the sun, we can use trigonometry.

Let's assume the length of the shadow is "s" and the height of the tower is "h". We know that the sun's rays are at an altitude of 45 degrees.

We can use the tangent function to calculate the length of the shadow:

tangent(angle) = opposite/adjacent

In this case, the opposite side is the height of the tower (h) and the adjacent side is the length of the shadow (s).

So, we have:

tan(45) = h/s

Now, we can rearrange the equation to find s:

s = h / tan(45)

Since tan(45) is equal to 1, we simplify the equation to:

s = h / 1

Therefore, the length of the shadow of a tower that is h meters high, with the sun at an altitude of 45 degrees, is equal to the height of the tower, h meters.

At 45° the length of the shadow will also be h m
