Question

cos41/sin49 evaluate​

Answer 1

Answer:

Step-by-step explanation:

Cos 41/ Sin 47

= cos( 90-41)/ sin47

= sin47/ sin47

= 1

Answer 2

Step-by-step explanation:

$\frac{ \cos(41) }{ \sin(49) } \\ \\ we \: know \: that = > \\ \sin(90 - a) = \cos(a) \\ \sin(41) \: can \: be \: written \: as \: \sin(90 - 49) \\ \sin(90 - 49) = \cos(49) ......(1) \\ \\ \\ from(1) = > \\ \\ \frac{ \cos(41) }{ \sin(49) } \\ \frac{ \cos(49) }{ \cos(49) } \: \\ 1$
