Answer:

1

Step-by-step explanation:

= tan 31° tan 33° tan 35º . . . tan 57° tan 59°

We know that,

tanA = cot (90- A)

= tan 31° tan 33° tan 35º . . . cot(90°-57°) cot (90°- 59°)

= tan 31° tan 33° tan 35º . . . cot33° cot31°

We know that,

cotA = 1/tanA

= tan 31° tan 33° tan 35º . . . 1/tan33° 1/tan31°

= 1
