Answer:


x=14

Explanation:


(5x-14)+(8x+12)=180

These two angles on the line is 180°

Solve the equation:


5x-14+8x+12=180


5x+-14+8x+12=180


(5x+8x)+(-14+12)=180 {combine the like terms}


13x-2=180


13x=180+2


13x=182


x=182/13


x=14

PROOF:

{substitute 14 in the place of x}


(5(14)-14)+(8(14)+12)=180


56+124=180


180=180

hope this helps....
