Answer:

x=12

Step-by-step explanation:

X=12 because we can see from the picture that the left line is drawn between parallel lines, meaning that the two angles (10x-13 and 4x+25) are supplementary, meaning that they add up to 180.

so we can now write an equation and solve it

(10x-13)+(4x+25)=180

14x+12=180

14x=168

x=12
