Question

If you can figure it out amazing!

find x​

Answer 1

Explanation:

exactly, the angles on opposite sides of the crossing point have to be equal.

for the same reason also the angles on the top and on the bottom of the crossing point are equal to each other.

just think about it - this has to be. otherwise you would have to bend the lines after the crossing point, which makes them no longer the same lines.

Answer 2

x + 17 = 3x -31 (opposite angles are equal)
x + 17 = 3x -31
31 +17 = 3x - x
48 = 2x
x = 24
