Answer 2

Step-by-step explanation:

opp angles are equal in a parallelogram = (7r -6)° and (5r +6)°

7r -6 = 5r +6

7r - 5r = 6 + 6

2r = 12

r = 12/2

r = 6

7r - 6 = 7×6 - 6

= 36

5r + 6 = 5×6+6

= 36

Sum of 2 angles = 72

Total sum of angles in a parallelogram = 360

360−72=288

288/2=144 ( other two angles)

Therefore angles are 36, 144 , 36 & 144.
