OK. Even though you only gave me part of the paragraph, I read that much, and I think I'm ready to select the correct answer now. What are the choices ?
QR and QS are perpendicular bisectors of the isosceles triangle XYX so QR= QS 1/2 x + 2 = x - 10 1/2 x - x = - 10 - 2 -1/2x = - 12 x = (-12) * (-2/1) x = 24
