Question

Determine the value of x for which rls if

.
m2i = 80 - X; and
mz2 = 90 - 2x
.

Answer 1

x = 10

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.
