Question

express sin 67 + cos 75 in the trigonometric. ratio of angles between 0 to 45​

Answer 1

We have

Sin(90 - θ) = Cosθ

Cos(90 - θ)= Sinθ

Coming to the question

$Sin 67 + Cos75$

$= Sin(90-23)+Cos(90-15)$

$= Cos23+Sin15$

HOPE IT HELPS !!

Answer 2

Answer:

cos 23+sin15

Step-by-step explanation:

$sin (90 - theta) = cos(theta) \\ \\ \cos(90 - theta) = \sin(theta)$
