polygon ABCDE is inscribed in a semi circle. The two points A and E at locations cos theta and -sin theta on the x-axis respectively, where 0<= theta < pi/2. As point C is fixed on the y-axis, all points except C shift positions where the value of theta changes. At a certain value of theta, it is found that the area of polygon equals to 41/50units square, and the length of AE equals to an irreducible fraction alpha/beta. What are the integers alpha and beta

Question

a polygon ABCDE is inscribed in a semi circle. The two points A and E at locations cos theta and -sin theta on the x-axis respectively, where 0<= theta < pi/2. As point C is fixed on the y-axis, all points except C shift positions where the value of theta changes. At a certain value of theta, it is found that the area of polygon equals to 41/50units square, and the length of AE equals to an irreducible fraction alpha/beta. What are the integers alpha and beta
