Question

Evalute the following and justify your answer.(1)sin^15°+sin^75°\cos^36°+cos 54°

Answer 1

Step-by-step explanation:

SIA then find cos A. then find secx. (ii) If tan x= 17 12 (111 25 If cosec = 7 then find cot O. TRY THIS Evaluate the following and justify your answer. sin? 15° + sin2 75° (1) sin 5° cos 85° + cos5° sin 85° cos2 36° + cos² 54° (111 sec 16° cosec 74° - cot 74º tan 16º. ple-13. Show that cot 0 + tan 0 = sec 0 cosec O. : LHS = cot 0 + tan
