Respuesta :

Answer:

3√58/58.

Step-by-step explanation:

The sine  is the opposite side / hypotenuse so we need to find its length.

By Pythagoras h^2 = 3^2 + 7^2

= 58.

So the hypotenuse h = √58.

So sine theta = 3 / √58.

Now multiply the top and the bottom of this fraction by √58, we get:

3√58/58.
