Hey, may I get some help, thank you so much.

C) sinF=27/45

Step-by-step explanation:

Because both triangles are similar, that means their sides are proportional to each other. Since sin∅=opposite/hypotenuse, then if sinC=3/5, we must find a ratio that is proportional to 3/5. Option C seems to work because 27/45=3/5, so sinF=27/45
