Answer 2

Step-by-step explanation:

$sin \: 30 \degree \: - sin \: 90 \degree \: + 2 \: cos \: 0 \degree \: = tan \: 30 \degree \: tan \: 60 \degree \\ lhs \: = sin \: 30 \degree \: - sin \: 90 \degree \: + 2 \: cos \: 0 \degree \\ = \frac{1}{2} - 1 + 2 \times 1 \\ = \frac{1}{2} + 1 \\ = \frac{3}{2} \\ \\ rhs = tan \: 30 \degree \: tan \: 60 \degree \\ = \frac{1}{ \sqrt{3} } \times \sqrt{3} = 1\\ \therefore \: lhs \neq rhs$
