=======================================================
Explanation:
The angles shown are alternate exterior angles. They are exterior of the parallel lines (ie outside the parallel lines) and they alternate on either side of the diagonal transversal cut.
If those alternate exterior angles are congruent, then lines L and M are parallel.
2x-3 = x+4
2x-x = 4+3
x = 7
Answer:
x = 7
Step-by-step explanation:
2x - 3 and x + 4 are alternate exterior angles with same measure
2x - 3 = x + 4
2x - x = 4 + 3
x = 7
