Question

if one of the two adjacent angles of a parallolegram is twice the other. then the measures of two angles are?

Answer 1

the first angle is 60 and second is 120

Answer 2

let one of the angles be x°
then other angle = 2x°

now since the sum of two adjacent angles of a parallelogram =180°

hence x+2x =180
=> 3x = 180
=>x= 60

hence measure of angles = 60° and 120° respectively
