Question

The adjacent angles of a parallelogram are ( 3y + 10 ) 0 and ( 3y – 4 ) 0 . Find the measure of the angles

Answer 1

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 2

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°
