    Let B=x degree In rhombus opposite angles are equal thus angle A= angle C=60degree Angle B=angle D=x degree We know that some of quadrilateral is 360 degree. Hence, A+B +C +D=360 60+x+60+x=360 2x+120=360 2x=360-120 2x=240 x=120 degree Hence Angle A = Angle B=60degree Angle B=Angle D=x=120degree
