Answer:
43°, 137°, 43°, 137°
Step-by-step explanation:
Opposite angles are equal.
5x-7 ° = (4x+3)°
5x -4x= 3+7
x = 10
5x-7 ° = 5(10)-7
= 50-7
= 43°
43° + adjacent angle = 180
adjacent angle = 180- 43°
adjacent angle = 137°

Step-by-step explanation:
in parallelogram opposite angles are equal
5x-7=4x+3
5x-4x=3+7
x=10
5x-7=5(10)-7=50-7=43
4x+3=4(10)+3=40+3=43
adjacent angles are supplementary
180-43=137
the four angles are 137,43,137,43
