If a tower 30 m high, casts a shadow `10sqrt3` m long on the ground, then what is the angle of elevation of the sun ?

Explanation

To find the angle of elevation of the sun when a tower of height 30 m casts a shadow of length \(10\sqrt{3}\) m, we can use trigonometric ratios. Here’s the step-by-step solution:

### Step 1: Identify the right triangle
We have a tower (height = 30 m) and its shadow (length = \(10\sqrt{3}\) m). This forms a right triangle where:
- The height of the tower is the perpendicular side (opposite side).
- The length of the shadow is the base (adjacent side).
- The angle of elevation of the sun is the angle we need to find.
