Solution

$\frac{s e c 29^{\circ}}{c o s e c 61^{\circ}}$ + $2 c o t 8^{\circ} c o t 17^{\circ} c o t 45^{\circ} c o t 73^{\circ} c o t 82^{\circ}$

= $\frac{s e c 29^{\circ}}{c o s e c (90^{\circ} - 29^{\circ})} + 2 c o t 8^{\circ} c o t 17^{\circ} (1) c o t (90^{\circ} - 17^{\circ}) c o t (90^{\circ} - 8^{\circ})$

= $\frac{s e c 29^{\circ}}{s e c 29^{\circ}}$ + $2 c o t 8^{\circ} c o t 17^{\circ} t a n 17^{\circ} t a n 8^{\circ}$

= $1 + 2 c o t 8^{\circ} c o t 17^{\circ} . \frac{1}{c o t 17^{\circ}} . \frac{1}{c o t 8^{\circ}}$

= 1+2

= 3
