If √2 Sin(60° - α) = 1, 0° < α < 90°, then α is equal to:
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 15°
| Understanding | Application |
|
Given √2 Sin(60° - α) = 1 |
⇒ Sin(60° - α) = 1/√2 |
|
We know: Sin45° = 1/√2 |
So, Sin(60° - α) = Sin45° Hence, α = 15° |
