Answer:
The correct option is 4.
Step-by-step explanation:
In a right angled triangle,
[tex]\sin \theta=\frac{perpendicular}{hypotenuses}[/tex]
In the given triangle it is clear that,
Hypotenuse = 13 cm
Perpendicular = 5 cm
Base = 12 cm
[tex]\sin x^{\circ}=\frac{5}{13}[/tex]
[tex]\sin x^{\circ}=5\div 13[/tex]
Therefore option 4 is correct.
