Question

Find the sine ratio of angle O (theta ).Hint: Use the slash symbol (/) to represent the fraction bar, and enter the fraction with no spaces.( Please help. This extra reference question is making me confuse .)

Answer 1

For angle theta, perpendicular side is AB = 12 and hypotenuse side is BC = 13.

The sine of angle is equal to the ratio of perpendicular side to the hypotenuse side. So sine of angle theta is,

`\sin \theta=(12)/(13)`

So sine ratio angle theta is 12/13.
