Bài tính, giúp mình với ạ

`A=\sin30^0+\sin60^0`

`A=1/2+(\sqrt{3})/(2)`

`A=(1+\sqrt{3})/(2)`

_______________________________________________

`A=\sin60^0+cos30^0`

`A=(\sqrt{3})/(2)+(\sqrt{3})/(2)`

`A=(\sqrt{3}+\sqrt{3})/(2)`

`A=(2\sqrt{3})/(2)`

`A=\sqrt{3}`

________________________________________________

`B=\cos60^0+cos30^0`

`B=1/2+(\sqrt{3})/(2)`

`B=(1+\sqrt{3})/(2)`

________________________________________________

`B=\sin30^0+\sin60^0+\cos45^0`

`B=1/2+(\sqrt{3})/(2)+(\sqrt{2})/(2)`

`B=(1+\sqrt{3}+\sqrt{2})/(2)`
