Answer:
x = 3
m<m = 114°
m<n = 66°
Step-by-step explanation:
✔️Opposite angles of a parallelogram are always congruent to each other.
Therefore:
m<m = 114°
m<n = 66°
✔️Opposite sides of a parallelogram are also congruent. This implies that:
7x - 3 = 4x + 6
Collect like terms
7x - 4x = 3 + 6
3x = 9
Divide both sides by 3
3x/3 = 9/3
x = 3
