Question

if one of angle of a parallelogram is 30 degree less than the twice of the smallest angle then find the measure of the each angle ​

Answer 1

Answer:

parallelogram has four sides so one angle is 30 another angles are also 30

Answer 2

Take the smaller angles as x. In a parallelogram the opposite angles are equal thus the opposite angle is x. Now take the other two angles as 2x-30. Now just add all 4 of them and solve like I did in the picture here.
