Is at an angle of 60 degrees, how tall is the tower?

We can use trigonometry to solve this problem. Let's denote the height of the tower as "h". The angle of elevation from the top of the tower to the tip of its shadow is 60 degrees.

Using the tangent function, we have:

tan(60 degrees) = h / 30m

Since the tangent of 60 degrees is √3, we can rewrite the equation as:

√3 = h / 30m

To solve for "h", we can multiply both sides of the equation by 30m:

√3 * 30m = h

Simplifying, we get:

h = 30√3 m

So, the height of the tower is approximately 51.96 meters.
