The adjacent angles of a parallelogram are in the ratio 2: 1 find all the angles

Adjacent angles of a parallelogram are supplementary. let the common multiple be x
2x+x= 180
3x=180
x=180/3
so x=60
therefore the angles are :
2x= 2*60 =120
&x=60.
the required angle are 120°,120°,60,°60°

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8
