TRIG PROBLEM HELP PLEASE

[MATH]\sin{\theta} = \dfrac{\text{opposite side}}{\text{hypotenuse}}[/MATH]
 
I see a 7 and a 4 that look misplaced … ?

Maybe they are the leg lengths since all the solution choices have [MATH]\sqrt{65}[/MATH] as a factor?

Why don’t you ask your instructor for clarification?
