the best method to solve such problems is to consider some trianglesay a right angled triangle with one vertex at 0,0 and one on x axis and another on y axis, then substitute the values of a and theta to zero down on the answerbut if u want proper methodi think the area of triangle when all vertices are given(matrix method) should work
