A right-angled triangle has 3 sides, which are the adjacent, the opposite and the hypotenuse. The sine ratio of an angle is the ratio of the opposite to the hypotenuse. The sine ratio of angle Θ is 4/5.
The given parameters are:
[tex]AB = 4[/tex]
[tex]AC =3[/tex]
[tex]BC =5[/tex]
The sine ratio of an angle is:
[tex]\sin(\theta) = \frac{Opposite}{Hypotenuse}[/tex]
In this case, the formula is:
[tex]\sin(\theta) = AB/BC[/tex]
So, we have:
[tex]\sin(\theta) = 4/5[/tex]
Hence, the sine of the angle is 4/5
