Answer:
= √3
Step-by-step explanation:
sin 15 × cos 75 + cos 15 × sin 75 / tan15 × tan 30 × tan35 × tan55 × tan 85
= sin 15 × cos(90-15) + cos(90-75) × sin 75 / tan30 × tan35 × cot35 × tan15 × cot15
= sin15 × sin15 + sin75 + sin75 / 1/√3 ×1
= sin^2 15 + sin^2 75 × √3
= sin^2 15 + cos^2 15 × √3
= 1 ×√3
= √3
