katrin2010 [14]

Answer:

b

Step-by-step explanation:

Using the trigonometric identities

cot x = \frac{cosx}{sinx} and tan x = \frac{sinx}{cosx} thus

\frac{cos0}{cot0} + tanΘ × cosΘ

= \frac{cos0}{\frac{cos0}{sin0} } + \frac{sin0}{cos0} × cosΘ

= cosΘ × \frac{sin0}{cos0} + sinΘ

= sinΘ + sinΘ

= 2sinΘ → b
