Ok, I could be wrong here, but here is what I would do. I would first set it up as an equation. I would set it up as 2x + 103 = 46 + x +57
However, I am not sure if this is 100% correct. But if it was me I would write my equation like this, and solve. I wrote it like this because 46 and x + 57 is equal to the measure of angle IJK, and the measure of the angle is 2x + 103.
From there, I would so love the equation.
If I am incorrect, please let me know. I hope this helps :)
