Answer 2

Все это табличные значения:

$tg45+sin150-cos90=1+0.5-0=1.5$

Answer 3

To solve the expression, let's first find the values of the trigonometric functions involved:

1. tg(45°) = tan(45°) = 1 (common trigonometric value)
2. sin(150°) = sin(180° - 30°) = sin(30°) = 0.5 (common trigonometric value)
3. cos(90°) = 0 (common trigonometric value)

Now, let's substitute the values into the expression and solve it:

tg(45°) + sin(150°) - cos(90°) = 1 + 0.5 - 0 = 1.5

So, the solution to the expression is 1.5.
