The value of tan 60° is:
Trigonometrical Ratios of Standard Angles
Original Khojo Papers practice question — not from a past board paper.
sin 30° = 1/2, cos 60° = 1/2 and tan 45° = 1
No citable source has been recorded for this record. Treat it as practice material, not as fact.
sin 30° and cos 60° are equal because the two angles are complementary.
