Answer 2

Answer:

$(4 - 5 \sqrt{3} ) \div 2$

Step-by-step explanation:

tan45=1

cos30=

$\sqrt{3 } \div 2$

sin60=

$\sqrt{3} \div 2$

so,

$= (2 \times 1 )+ 4 \times (\sqrt{3} \div 2) - 9 \times ( \sqrt{3} \div 2)$

$2 + 2 \sqrt{3} - (9 \sqrt{3} \div 2)$

lcm of 2

$=[4+ 4\times (\sqrt{3}) - 9\times (\sqrt{3})] \div 2$

you will get answer
