plz help
a diagram with line m parallel to line n is shown express the value of y in terms of x

Answer 1

Answer:

y = 170 - 3x

Step-by-step explanation:

l // m

y + 3x + 10 = 180  {co interior angles are supplementary}

 y + 3x   = 180 - 10   {Subtract 10 from both sides}

   y+ 3x = 170      {Subtract 3x from both sides}

          y = 170 - 3x
