By Sine Rule,
x/sin30° = 8/sin90°
x/0.5 = 8/1
So x = 4.
Notice the picture
the rhombus, or kite, is really just 4 triangles
all sides are the same lenght in a rhombus,
thus, find the area of all of the triangles,
and you already have two sides given,
and then, add them up
or just find the length of one, and multiply times 4 :)
recall, area of a triangle = 1/2 bh
84/56=1.5 - it is 1% of number
1.5*100=150
