(Sin 30°+cos 30 °) - (sin 60 °+cos60 °)

1.	(Sin 30°+cos 30 °) - (sin 60 °+cos60 °)
Answer» answer is 1 \xa0A n s w e r :=> (sin30+cos30) - (sin60+cos60)\xa0sin30 = 1/2\xa0sin60= √3/2\xa0cos30= √3/2\xa0cos60= 1/2\xa0=> (1/2+√3/2) - (√3/2+1/2)\xa0=> 1+√3/2 - √3+1/2\xa0=> 1+1+√3-√3 /2\xa0=> 2/2\xa0=>1
