The two labeled angles are alternate interior angles, and as such, they are the same.
From this result you can build the equation
![15x-2 = 13x+2](https://tex.z-dn.net/?f=%2015x-2%20%3D%2013x%2B2%20)
and solve it for x: subtract 13x from both sides to get
![2x-2=2](https://tex.z-dn.net/?f=%202x-2%3D2%20)
and add 2 to both sides to get
![2x = 4 \implies x = 2](https://tex.z-dn.net/?f=%202x%20%3D%204%20%5Cimplies%20x%20%3D%202%20)
Check: if we plug the value we found we have
![13\cdot 2 + 2 = 26+2 = 28 = 15\cdot 2 - 2 = 30-2](https://tex.z-dn.net/?f=%2013%5Ccdot%202%20%2B%202%20%3D%2026%2B2%20%3D%2028%20%3D%2015%5Ccdot%202%20-%202%20%3D%2030-2%20)
So the angles are actually the same, as requested.
The value of the digit in the tens place is 100 times as much as the value of the digit in the thousands place.
