Tick the correct answer and justify: In `DeltaA B C`.AB = `6sqrt(3)`cm. AC = 12 cm and BC = 6 cm. The angle B is:
(A) 120 (B) 60 (C) 90 (D) 45

Explanation

To find the angle B in triangle ABC where AB = \(6\sqrt{3}\) cm, AC = 12 cm, and BC = 6 cm, we can use the Pythagorean theorem. Here are the steps to solve the problem:

### Step 1: Identify the sides of the triangle
We have the following sides:
- AB = \(6\sqrt{3}\) cm
- AC = 12 cm (this will be considered as the hypotenuse)
- BC = 6 cm
