Hello,
Step-by-step explanation:
Let's assume A,B,C the 3 explorers and X,Y,Z the 3 guides.
Only A and X can operate the boat.

I hope you will understand the travels
The two labeled angles are alternate interior angles, and as such, they are the same.
From this result you can build the equation

and solve it for x: subtract 13x from both sides to get

and add 2 to both sides to get

Check: if we plug the value we found we have

So the angles are actually the same, as requested.
All are correct because negative numbers are always smaller than 0 and bigger negative numbers always are less then smaller negative numbers such as -9 is smaller than -5
Answer: A reflection across the x-axis keeps the x-coordinates the same but flips the signs of the y-coordinates. So, it should be the opposite for a reflection across the y-axis. The y-coordinates remain the same, but the signs of the x-coordinates change.
