Answer 1

Step-by-step explanation:

sin30degree =1/2

cos 30 degree= √3/2

and,

sin 45 degree= cos 45 degree = 1/√2

putting these values in given question you can easily solve the problem

I hope it will help you

Answer 2

according to the formulasin(a). cos(b) +cos(a). sin(b) =sin(a+b)

sin(30+45)

sin(75)

1+√3/2√2
