In a kite, two opposite angles are equal. In this case, angle K is equal to angle M. And since the angles in a kite add up to 360 in a quadrilateral, we can get the equation, 2x+48+70=360 where x is angle K or angle M and so solve for x 2x+118=360 2x=242 x=121 Angle K = 121 degrees Hope this helps.
