Question

ZiI really need some help on this one because I don't know how to do it

Answer 1

The trigonometric ratio sin (θ) is used to find angles of right triangles and is given by:

`\sin (\theta)=\frac{\text{Opposite side}}{\text{ Hypotenuse}}`

Graphically,

So, in this case, you have:

`\begin{gathered} \sin (K)=(5)/(10) \\ \text{Simplifying} \\ \sin (K)=(5\cdot1)/(5\cdot2) \\ \sin (K)=(1)/(2) \end{gathered}`

Therefore, the correct answer is option A.
