Options
- A135°
- B45°
- C90°
- D60°
Correct answer
B. 45°
Step-by-step solution
As per the diagram, the distance between Dev and Bani is 40 m while the distance between Dev and Teenu is also 40 m. Clearly, if we connect the points Bani, Dev and Teenu, they will form an isosceles triangle with angle BDT (Bani,Dev,Teenu) to be 90°. Therefore, the angle BTD(Bani,Teenu,Dev) must be 45°. Option B is hence the correct answer.
