http://i.imgur.com/3dAFKoJ.png since it looks like an equilateral triangle but it's not so I have no idea sure if I should use sin or cos.

    It's not equilateral as the sides are not congruent. We know that \[A = \frac{ 1 }{ 2 }bh\] but this is for a right angle triangle |dw:1438328568192:dw| so using this as a reference to draw a new picture

    |dw:1438328622099:dw| so for a non right angle triangle we can use the area \[A = \frac{ 1 }{ 2 }absinC\]

    \[A = \frac{ 1 }{ 2 }acsinB\] so for you use this

    This isn't equilateral triangle. An equilateral triangle has 60 degrees angle on each sides
