Question

Tan40/cot50+sin^20+sin^20+tan50×tan10×tan60+tan80/cot85

Answer 1

Step-by-step explanation:

Sin18/cos (90 - 18 ) + root 3 ( tan (90 - 80) tan (90 - 50) tan 45 tan50 tan 80)

sin18/sin18 + root 3 ( cot 80 cot 50 tan 45 tan50 tan 80)

1 + root 3(1)

1 + 1 = 2 ANSWER.

note - it should be tan 45 instead of tan 40.

thanks...
