Question

opposite angles of Parallelogram

5x-7 °' and (4x+3)° Find all angles​

Answer 1

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°

Answer 2

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
