Nilai dari sin 75°+sin 15°=dots A. (1)/(2)sqrt6 B. 1 C. (1)/(2)sqrt3 D. (1)/(2)sqrt2 E. (1)/(2)
Jawaban
None of the given options (A, B, C, D, E) correctly match the calculated value.
Penjelasan
The question requires finding the value of sin75° + sin15°. To solve this, we use the trigonometric function sine (sin) and apply it to the angles 75° and 15°.
1. Convert the angles 75° and 15° to radians since trigonometric functions in many computational systems use radians. The conversion formula is \(\text{radians} = \text{degrees} \times \frac{\pi}{180}\).
2. Calculate sin75° and sin15° using the sine function.
3. Add the values of sin75° and sin15° to get the final result.
After performing these steps, the calculated value of sin75° + sin15° is approximately 1.2247. This value does not exactly match any of the given options (A, B, C, D, E). Therefore, it seems there might be an error in the options provided, or a different approach or simplification is needed to match one of the given options.
