If one angle of a parallelogram is 24° less than twice the smallest angle then the largest angle of the parallelogram is


Let A = x°,


B = (2x – 24)°


C = x° (Opposite angles are equal.)


D = (2x – 24)° (Opposite angles are equal.)


Since the sum of angles of a parallelogram is 360°,


A + B + C + D = 360°


x° + (2x – 24)° + x° + (2x – 24)° = 360°


6x° – 48 =360°


6x° = 408°


x° = 68°


A = 68°


B = (2x – 24)° = 112°


Therefore, largest angle of the parallelogram is 112°.
