Answer:
97, 83
Step-by-step explanation:
adjacent angles sum is 180 in parallelogram
so,
3y + 10+ 3y – 4= 180
6y+6=180
6y=180-6
6y=174
y=174/6
y=29
3y+10= 3*29+10=97
3y-4=3*29-4=83
I hope my answer helps you☺☺
Answer:
Step-by-step explanation:
in parallelogram opp angles are equal
sum of all angles in a parallelogram is 360°
⇒ 2(3y + 10) + 2(3y - 4) = 360
⇒ 6y + 20 + 6y - 8 = 360
⇒ 12y + 12 = 360
⇒ 12y = 360 - 12 = 348
⇒ y = 348/12 = 29
so the angles are 97° and 83°
