Answer:

C

Step-by-step explanation:

note that sin x = cos(90 - x ) ← Cofunction identity

If x = 36 then 90 - x = 90 - 36 = 54

Hence sin 36° = cos 54° → C

Can someone help me with this question please.
sineoko [7]

Answer: y = 85 2) 36.222°

Step-by-step explanation:

281 + 268 + 225 + 290 = 1064

1064 / 7 = 152

152 x 12 = 1824

392 + 512 + 413 + 422 = 1739

1824 - 1739 = 85

Therefore y = 85
