Answer 1

Answer:

job in this to the store with the to yours or the day after I

Answer 2

$\huge\tt\colorbox{teal}{Answer}$

$sin60 = \frac{ \sqrt{3} }{2} \\ \\ cos \: 30 = \frac{ \sqrt{3} }{2} \\ \\ sin30 = \frac{1}{2} \\ \\ cos60 = \frac{1}{2}$

$sin \: 60 \times cos \: 30 + sin30 \times cos60 \\ \frac{ \sqrt{3} }{2} \times \frac{ \sqrt{3} }{2} + \frac{1}{2} \times \frac{1}{2} \\ \\ \frac{ { (\sqrt{3}) }^{2} }{ {2}^{2} } + \frac{1}{4} \\ \\ \frac{3}{4} + \frac{1}{4} \\ \\ \frac{3 + 1}{4} \\ \\ \frac{4}{4} \\ 1$

$option \: b)1 \: is \: the \: correct \: answer$
