sin (5x - 25°) = cos(5y + 25°), ఇక్కడ 5x - 25° మరియు 5y + 25° తీవ్రమైన కోణాలు,
ఉపయోగించిన భావన:
Sinθ = cos (90°- θ)
గణన:
ప్రశ్న ప్రకారం,
sin (5x - 25°) = cos(5y + 25°)
⇒ sin (5x - 25°) = sin 90 - (5y + 25°)
⇒ (5x - 25°) = 90° - (5y + 25°)
⇒ 5x + 5y = 90
⇒ x + y = 90/5
⇒ x + y = = 18°
∴ సరైన ఎంపిక 3
