If two parallel lines are cut by a transversal, then the pairs of consecutive interior angles formed are supplementary. In this example, angle DHI and GIC will be supplementary. Therefore, they will sum to be 180 degrees. We can use algebra to solve this.


(15x-8)+(128-3x)=180\\12x+120=180\\12x=60\\x=5

Therefore, x is equal to 5 degrees. I hope you find this helpful, and please feel free to ask any questions if necessary. ;)
