What are inequalities?
Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed.
It is mostly denoted by the symbol <, >, ≤, and ≥.
The statement that is true about 192° can be found by simplifying the given expression. Therefore, The value of the options can be simplified as shown below,
Cos(192°) > 0 ⇒ -0.978 > 0
Tan(192°) < 0 ⇒ 0.212 <0
Sin(192°) < 0 ⇒ -0.2079 < 0
As it can be observed that only the third inequality is true. Therefore, the statement that is correct about 192° is option C.
