Answer:

$\frac{4}{3}$

Step-by-step explanation:

sec 41° . sin 49 + cos 29° cosec 61° - 2/√3 ( tan 20°. tan 60 . tan 70) / 3(sin²31° + sin²59°)

⇒cosec (90°- 49°) . sin 49° + cos 29° sec (90° -29°) - 2/√3 (tan 20°. √3 . cot (90° - 20°)) / 3(sin²31° + cos²(90° - 31°))

⇒cosec 49° . sin 49° + cos 29° sec 29° - 2/√3 (tan 20° . √3 . cot 20°) /  3(sin²31° + cos²31°)

⇒1 + 1 - 2/√3 (1 . √3)) /  3(1) = 1 + 1 - 2/√3 (√3) /  3

⇒1 + 1 + 2 / 3 = 4/3
