• Is $\frac{5}{4}$, possible value of $\sin x$? Explain.

$\star\:\:\:\bf\large\underline\blue{Answer:-}$

• No, it's impossible. In a triangle,sine of any angle is the ratio of the perpendicular to the hypotenuse of the triangle but we know that hypotenuse cannot be greater that other two sides, so the ratio must be less than or equal to 1. So, sin of x cannot be 5/4.
