Answer 2

Let's start by simplifying the expressions inside the parentheses:

1 + sin 30 = 1 + 0.5 = 1.5

2√3 - sin 60 = 2√3 - √3/2 = (4√3 - 3)/2

Now we can substitute these values into the original expression and simplify:

(1 + sin 30)(2√3 - sin 60) = (1.5)(4√3 - 3)/2 = (3√3 - 9/2)

Therefore, (1 + sin30)(2√3 - sin60) simplifies to (3√3 - 9/2).
