Answer 2

$answer$..

${ \tan }^{2}$

$30 \sin \: 30 + \cos \: 60 \: \sin2$

$90 \tan2$

$60 - 2 \tan \: 45 \: \cos \: 2$

$0 \: \sin \: 90 = (3)$

$1)2$

$2)1 + 21 \times 1 \times (3)2.$

$- 2x1 \times 1 \times 1 \times = 61 + 23$

$- 2 = 6$

$1 + 9 - 12 = 6 - 2 = 3 = - 1$

$hence \: the \: answer \: is$

$3 - 1$
