Answer 1

Sine = opposite / adjacent.

since the opposite and adjacent lines are used, you need to use some to solve for x.

the answer is sine.

Answer 2

Answer:

The correct answer is A which is sine.

Step-by-step explanation:

The variable $x$ is opposite to the known angle and the known side length which is the hypotenuse.

Recall the mnemonics SOH, which means that,
the sine ratio involves the length of the opposite side and the hypotenuse.

That is,

$\sin50\degree=\frac{opposite}{hypotenuse}$

$\sin50\degree=\frac{x}{2}$

We can use this to solve for $x$.
