HEY DEAR HERE IS UR ANSWER
= tan (90° − 42°) tan (90° − 67°) tan 42° tan 67°
= cot 42° cot 67° tan 42° tan 67°
= (cot 42° tan 42°) (cot 67° tan 67°)
= (1) (1)
= 1
HOPE IT HELPS
THANK U

Hi Friend !!!
=================
tan 48 = cot 42
= 1/tan42
tan 23 = cot 67
= 1/ tan 67
tan48 tan23 tan42 tan67
= 1/tan42 × 1/tan67 × tan42 × tan67
= 1
Hope it helps u :-)
