Answer 2

Ответ:

2sin30sin60-tg45cos30=√3/2-√3/2=0

Answer 3

To solve the expression, let's break it down step by step:

1. sin(30) = 1/2
2. sin(60) = √3/2
3. cos(30) = √3/2
4. tan(45) = 1

Now, substituting these values into the expression:

2sin30sin60 - tg45cos30

= 2(1/2)(√3/2) - (1)(√3/2)

= (√3/2) - (√3/2)

= 0

Therefore, the value of the expression 2sin30sin60 - tg45cos30 is 0.
