What is the value of sin 47°?

The value of sin 47° is approximately 0.731.

Explanation:

• 47° is not a standard angle like 30°, 45°, or 60°
• Therefore, its value is obtained using trigonometric tables or a calculator

So,
sin 47° ≈ 0.731

Key point:

• For most numerical problems, this approximate value is sufficient
• In exams, values may be rounded to two or three decimal places
