What is the length of the support ab?

answers:
9 cos 60°
9 divided by tan 60 degrees
9 divided by sin 60 degrees
9 sin 60°

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

now, we can plug values

and we get

now, we can solve for AB

we get

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