1. Two opposite angles of a parallelogram are (3x - 2) and (50 – 3)". Find the measure
of each angle of the parallelogram.
Answers
Step-by-step explanation: opp angle of a parallelogram are congruent so,
3x-2=50-x
3x+x=50+2
4x=52
x=52/4
x=13
one of the angle =3x-2
= 3(13)-2=37 degree
opp angle = 50-x
= 50-13=37 degree
Let the other two angles = y and z
y=z (opp angle)
sum of all angles =360 degree
37+37+y+z=360 degree
74+y+z= 360 degree
y+z=360-74
y+z=286 degree
y=z (opp angle)
y+y=286 degree
2y=286 degree
y=286/2=143 degree
four angles of parallelogram=
