Question

Two opposite sides of a parallelogram each have a length of `4`. If one corner of the parallelogram has an angle of `(11 pi)/12` and the parallelogram's area is `48`, how long are the other two sides?

Answer 1

`=46.36`

Explanation:

Area`=ab sin theta` where `a=4;theta=11pi/12 and Area =48`
We have to find `b=?`
So
`4b sin(11pi/12)=48`
or
`b(0.2588)=48/4`
or
`b=12/0.2588`
or
`b=46.36`
