Answer 2

Let's assume

A is our angle

here , we have A=60

so, opposite=BC=9feet

we have to find AB

here , AB is hypotenuse

so, we can use sine formula

`sin(A)=(BC)/(AB)`

now, we can plug values

and we get

`sin(60)=(9)/(AB)`

now, we can solve for AB

we get

`AB=(9)/(sin(60))`

so, option-C..........Answer
