Question

Determine the value of x for which rls if . m2i = 80 - X; and mz2 = 90 - 2x .

Answer 1

Answer:

  x = 10

Step-by-step explanation:

For the lines to be parallel, the two angles must have the same measure:

  80 - x = 90 - 2x

  x = 10 . . . . . . . . . add 2x-80

The value of x must be 10 to make the lines parallel.
