Answer 2

Step-by-step explanation:

As i understand ur question..

$\frac{ \cos(20) }{ \sin(70) } + \frac{ \cos(\theta) }{ \sin(90 - \theta) } \\ \\ note \: \: sin(90 - \theta) = \cos(\theta) \\ \\ = \frac{ \cos(20) }{ \sin(90 - 20) } + \frac{ \cos(\theta) }{ \sin(90 - \theta) } \\ \\ = \frac{ \cos(20) }{ \cos(20) } + \frac{ \cos(\theta) }{ \cos(\theta) } \\ \\ = 1 + 1 \\ \\ = 2$
