Answer:
First option and Fourth option.
Step-by-step explanation:
To solve this exercise you need to use the following Trigonometric Identity:
![sin\alpha=\frac{opposite}{hypotenuse}](https://tex.z-dn.net/?f=sin%5Calpha%3D%5Cfrac%7Bopposite%7D%7Bhypotenuse%7D)
In this case you know that:
![\alpha =C](https://tex.z-dn.net/?f=%5Calpha%20%3DC)
Since triangle ABC is similar to triangle DEF:
![\angle C=\angle F](https://tex.z-dn.net/?f=%5Cangle%20C%3D%5Cangle%20F)
Let's begin with the triangle ABC.
You can identify that:
![opposite=AB\\hypotenuse=AC](https://tex.z-dn.net/?f=opposite%3DAB%5C%5Chypotenuse%3DAC)
Then, substituing values, you get:
![sinC=\frac{AB}{AC}](https://tex.z-dn.net/?f=sinC%3D%5Cfrac%7BAB%7D%7BAC%7D)
In triangle DEF, you know that:
![opposite=DE\\hypotenuse=DF](https://tex.z-dn.net/?f=opposite%3DDE%5C%5Chypotenuse%3DDF)
So, substituing values, you get:
![sinF=sinC=\frac{DE}{DF}](https://tex.z-dn.net/?f=sinF%3DsinC%3D%5Cfrac%7BDE%7D%7BDF%7D)
The area model you can use is D , cs 70 +3 & 30+9
