Detailed Solution
Download Solution PDFदिया गया है:
sin (A - B) = \(\frac{1}{2}\), sin(A + B) = 1
गणना:
sin (A - B) = \(\frac{1}{2}\)
⇒ sin (A - B) = sin 30°
⇒ (A - B) = 30°
पुनः,
sin(A + B) = sin 90°
⇒ (A + B) = 90°
इसलिए,
(A - B) + (A + B) = 90° + 30°
⇒ 2A = 120°
⇒ A = 60°
और B = 30°
∴ सही विकल्प 2 है
