Answer:
sinF = 3
/5 or 0.6.
Explanation:
Triangle ABC is a right triangle with its right angle at B. Therefore, AC is the hypotenuse of right triangle ABC, and AB and BC are the legs of right triangle ABC. According to the Pythagorean theorem,
AB=√202−162=√400−256=√144=12
Since triangle DEF is similar to triangle ABC, with vertex F corresponding to vertex C, the measure of angle∠F equals the measure of angle∠C. Therefore, sinF=sinC. From the side lengths of triangle ABC,
sinF = oppositeside
/hypotenuse = AB
/AC = 12/
20 = 3
/5

I hope this gives you some sort of assistance.
Reread the textbook just to make it better <em>(if you can quickly look through it)</em>
Anyways goodluck!

um i dont understand what you are trying to say here could you be more specific
