Задание

Вычисли синус, косинус и тангенс угла $150\degree$.

Выбери верные варианты из списков.

$cos 150\degree = cos (90\degree$ [+|-] [30|60|90|150]$\degree$$ ) =$ [+|-] [sin |cos|tg][30|60|90|150]$\degree =$ [+|-] $\dfrac{\sqrt3}{2}$.

$sin 150\degree = sin (180\degree $[+|-] [30|60|90|150]$\degree) =$ [+|-][sin|cos|tg][30|60|90|150]$\degree =$ [+|-]$ \dfrac{1}{2}$.

$tg 150\degree = sin$ [30|60|90|150] $\degree : cos$ [30|60|90|150] $\degree =$ [+|-] $ \dfrac{\sqrt3}{3}$.
