Respuesta :

[tex] \sin(A) = \frac{BC}{AB} = \frac{a}{c} [/tex]

Answer:

[tex] sinA = \frac {a} {c} [/tex]

Step-by-step explanation:

We are given a right angled triangle ABC with the side lengths a, b and c. We are to find the value of sin A.

We know that sine is the ratio of perpendicular to hypotenuse.

So considering A as our desired angle, side a will be our perpendicular while c will be the hypotenuse.

Therefore, [tex] sinA = \frac {a} {c} [/tex].
