A TV-tower stands vertically on a bank of a canal. From a point on the other bank directly opposite the tower, the angle of elevation of the top of the tower is `60^(@)`. From another point 20 m away from this point on the line joining this point to the foot of the tower, the angle of elevation of the top of tower is `30^(@)` (see fig.) . FInd the height of the tower and the width of the canal.

Explanation

To solve the problem, we will follow these steps:

### Step 1: Define the variables
Let:
- \( h \) = height of the tower (in meters)
- \( x \) = width of the canal (in meters)

### Step 2: Analyze the first triangle
