Question

(sin30 + cos45 ) ( sin60 + cos30)

Answer 1

$( \sin30 + \cos45)( \sin60 + \cos30) \\ \\ now \: put \: the \: values \: of \: all \: trigonometry \: angles \\ ( \frac{1}{2} + \frac{1}{2} )( \frac{ \sqrt{3} }{2} + \frac{ \sqrt{3} }{2} ) \\ ( \frac{2}{2} )( \frac{2 \sqrt{3} }{2} ) \\ 1 \times \sqrt{3} = \sqrt{3} = 1.732 \: \: ans$

Answer 2
